-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Summary Report Announcement-ID: SUSE-SR:2004:002 Date: Tuesday, Nov 30th 2004 14:00 MEST Cross References: CAN-2004-0504 CAN-2004-0505 CAN-2004-0506 CAN-2004-0507 CAN-2002-0029 CAN-2004-0888 CAN-2004-0889 CAN-2004-0986 Content of this advisory: 1) solved security vulnerabilities: - perl-Archive-Zip file evasion problem - evolution certificate handling - resmgr fake tty addition - xpdf issues: tetex - abiword / wv buffer overflows - iptables - uninitialised variable - gnome-vfs issues - glibc missed buffer overflow fixes - ethereal protocol handler problems 2) pending vulnerabilities, solutions, workarounds: - kernel problems - cyrus-imapd remote problems - Sun Java Plugin - setuid perl permissions 3) standard appendix (further information) ______________________________________________________________________________ 1) solved security vulnerabilities To avoid spamming lists with advisories for every small incident, we will release weekly summary advisories for issues where we have released updates without a full advisory. Since these are minor issues, md5sums and ftp urls are not included. Fixed packages for the following incidents are already available on our FTP server and via the YaST Online Update. - perl-Archive-Zip perl-Archive-Zip are Perl modules to handle extraction of ZIP archives. These had the bug that for certain invalid headers, extracted files could have the size 0 shown, but otherwise were extracted correctly. This trick could have been used by virus authors to fool virus scanners. It was found by iDEFENSE security, refer to this URL: http://www.idefense.com/application/poi/display?id=153 All SUSE Linux based products are affected. - evolution There was a problem in the evolution SSL certificate handling which lead to always untrusted certificates. All SUSE Linux based products up to SUSE Linux 9.1 and SUSE Linux Enterprise Server 9 are affected. - resmgr resmgr is used for handling permissions of normal desktop based devices (audio, video, USB, and similar) in a safe and secure way. It was possible for a remotely logged in user to gain access to the virtual desktop group, indirectly gaining access to the desktop devices. SUSE Linux 8.2 up to 9.2, and SUSE Linux Enterprise Server 9 are affected. - tetex tetex contains PDF processing tools, which were affected by the xpdf integer and buffer overflow vulnerabilities already reported. The xpdf issues are tracked by the Mitre CVE Ids CAN-2004-0888 and CAN-2004-0889. All SUSE Linux based products are affected. - abiword abiword contains the Microsoft Word compatibility library "wv". Several months ago we fixed buffer overflow issues in the "wv" library, this is an update fixing the problem in the copy of "wv" in abiword. Only SuSE Linux 8.1 is affected by this problem. - iptables The iptables program used an uninitialized variable to find out about the module loader for the first module loaded (ip_tables). In rare cases it was possible that this could lead to this module not being loaded and iptables based firewalls not activated at all. We were not able to reproduce this and have no reports of this happening, however we have released fixed packages nethertheless. This is tracked by the Mitre CVE Id CAN-2004-0986. All SUSE Linux based products are affected. - gnome-vfs Several GNOME vfs handlers had problematic code, for instance unsafe argument evaluation and similar. We released updates fixing the known issues. All SUSE Linux based products are affected. - glibc A buffer overflow fix in the resolver libraries of glibc 2.2 was found missing. Reference is the Mitre CVE Id CAN-2002-0029. Fixed packages are available. SUSE Linux 8.1 and SUSE Linux Enterprise Server 8 are affected by this problem. - ethereal Several protocol handlers in the network analysis tool ethereal had security problems which could lead bad network input to ethereal crashing. These crashes are tracked by the Mitre CVE Ids CAN-2004-0504, CAN-2004-0505, CAN-2004-0506, and CAN-2004-0507. All SUSE Linux based products are affected. ______________________________________________________________________________ 2) Pending vulnerabilities in SUSE Distributions and Workarounds: - kernel Several problems have been found in the Linux 2.4 and 2.6 kernels: - Several issues have been found in the error handling of the ELF loader routines by Paul Starzetz of isec.pl. These are tracked by the Mitre CVE Ids: CAN-2004-1070,CAN-2004-1071,CAN-2004-1072 CAN-2004-1073. - Several overflow checks in the smbfs handling of both Linux 2.4 and 2.6 were found missing by Stefan Esser. This is tracked by the Mitre CVE Id CAN-2004-0883. - Handcrafted a.out binaries could be used to trigger a local denial of service condition in both 2.4 and 2.6 Linux kernels. Fixes for this problem were done by Chris Wright. This is tracked by the Mitre CVE Id CAN-2004-1074. - A very small race window was found in the memory management of the kernel which could be used to show the content of random physical memory pages potentially leading to information disclosure. This is already fixed in the mainline kernel. These bugs affect all SUSE Linux products. We are in the process of releasing updated packages. - cyrus-imapd Remote buffer overflow possibilites in the Cyrus IMAP daemon were found by Stefan Esser and Sebastian Krahmer. All SUSE Linux based products are affected. - Sun Java Plugin A privilege escalation problem was found in the Sun Java Plugin which could have a remote attacker reading and writing files of a local user browsing websites. This bug affects all SUSE versions on the Intel x86 and AMD64 / Intel Extended Memory Architecture (EM64T) platforms. We are in the process of releasing updated Java packages. - perl SUSE LINUX 9.2 follows the new upstream policy to install /usr/bin/suidperl as hardlink to /usr/bin/perl. In previous perl versions it used to be a hardlink to /usr/bin/sperl*. Therefore one must not set a setuid bit on /usr/bin/suidperl as suggested in the rpm package description of perl. Set the bit on /usr/bin/sperl5.8.5 instead if you really need the suid feature. Also check your /etc/permissions.local file for references of /usr/bin/suidperl if you where upgrading from previous SUSE LINUX releases. SUSE Linux is not affected by this problem in the default installation, only if the administrator added the s-bit to suidperl. ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SUSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SUSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We recommend against subscribing to security lists that cause the e-mail message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the file name of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SUSE in rpm packages for SUSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SUSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the top-level directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe(a)suse.com>. suse-security-announce(a)suse.com - SUSE's announce-only mailing list.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Summary Report Announcement-ID: SUSE-SR:2004:001 Date: Wednesday, Nov 24th 2004 12:00 MEST Cross References: CAN-2004-0956 CAN-2004-0835 CAN-2004-0836 CAN-2004-0957 CAN-2004-0837 CAN-2004-0885 CAN-2004-0940 CAN-2004-0942 Content of this advisory: 1) solved security vulnerabilities: - ImageMagick integer overflow in EXIF handling - acpid directory world writable problem - several mysql bugs - perl-MIME-Tools mime boundary handling - apache denial of service - apache1 / mod_include local buffer overflow - apache2 / mod_SSL cipher suite bypass - tftp buffer overflows - xpdf integer overflows - xine-lib buffer overflows - gd integer overflows 2) pending vulnerabilities, solutions, workarounds: - kernel problems 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion To avoid spamming lists with advisories for every small incident, we will release weekly summary advisories for issues where we have released updates without a full advisory. Fixed packages are available on our FTP server and via the YaST Online Update. - ImageMagick ImageMagick is an collection of command-line tools and libraries to manipulate images. The EXIF JPEG tag handling routines had a integer overflow which could lead to memory being overwritten. - acpid acpid is a daemon watching for ACPI status changes and key presses. A bad umask handling lead to acpid creating a world writable directory. - mysql Several problems were found in the mysql database server. CAN-2004-0956: Crash with MATCH..AGAINST. CAN-2004-0835: Privilege escalation in ALTER TABLE RENAME. CAN-2004-0836: Potential Memory Overrun With Compromised DNS Server. CAN-2004-0957: Privilege Escalation on GRANT ALL ON `Foo\_Bar` CAN-2004-0837: Concurrent accesses to MERGE tables can result in crash. Also, the mysqlhotcopy /tmp file handling fix from the last security update was broken. - Apache Several problems were found in the Apache web servers: CAN-2004-0885: mod_ssl SSLCipherSuite bypass, where an attacker could bypass a fixed list of ciphers and use a less secure one. CAN-2004-0940: mod_include local buffer overflow, where a local attacker could execute code in the local apache process if mod_include is enabled. CAN-2004-0942: Fix of memory consumption denial of service attack with HTTP continuation headers. We are in the process of releasing packages. - perl-MIME-Tools The perl-MIME-Tools are perl modules that do parsing of MIME E-mail bodies. These modules are used for instance by the amavisd-new and potentially other virus scanners. Due to an input error handling, some attachments can bypass the virus scanner. - tftp The tftp daemon had several buffer overflows, which could potentially be used by a remote attacker to gain local access. - xpdf We released xpdf buffer and integer overflow patches some weeks ago. We found that these fixes still have problems on 64 bit systems. Additional fixes were done by us and we are in the process of releasing updates, for xpdf, gpdf, pdftohtml, cups (which includes pdftops) and tetex (which also contains xpdf code). - xine-lib Several string based overflows were found in the XINE libraries. This is issue is tracked by the Xine security ID XSA-2004-4. - gd An integer overflow that might lead to a buffer overflow was found in the PNG image loader routines of the GD graphics library. ______________________________________________________________________________ 2) Pending vulnerabilities in SUSE Distributions and Workarounds: - kernel Several problems have been found in the Linux 2.4 and 2.6 kernels: - Several overflow checks in the smbfs handling of both Linux 2.4 and 2.6 were found missing by Stefan Esser. - Handcrafted a.out binaries could be used to trigger a local denial of service condition in both 2.4 and 2.6 Linux kernels. Fixes for this problem were done by Chris Wright. - A very small race window was found in the memory management of the kernel which could be used to show the content of random physical memory pages potentially leading to information disclosure.

A source code review done by Thomas Biege of the SuSE Security-Team revealed several different kinds of bugs. The bug types are: - integer overflows - out-of-bounds memory access - shell command execution - path traversal - endless loops By providing a special image these bugs can be exploited by remote and/or local attackers to gain access to the system or to escalate their local privileges. 2) solution/workaround No workaround exists to protect against these bugs. 3) special instructions and notes Please restart the X server or switch to runlevel 3 and back to 5 to make sure every GUI application is restarted and uses the new library. 4) package location and checksums Download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. Our maintenance customers are being notified individually. The packages are being offered for installation from the maintenance web. Smalltalk is the only package using libxpm statically. It will be available via YOU too. x86 Platform: SUSE Linux 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/xorg-x11-libs-6.8.1-15… 395edf444f05b448aa7c7e70455333ce patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/xorg-x11-libs-6.8.1-15… 8d215ce255838120c70ba77ad944a84f source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/src/xorg-x11-6.8.1-15.3.src… 3889aee5895035c57c716f370f5e414a SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/XFree86-libs-4.3.99.90… 89431783cd8261a970d6ec5484dd09e6 patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/XFree86-libs-4.3.99.90… 8ea579d10465143a2334be812f23561e source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/XFree86-4.3.99.902-43.3… a37eaa7e7b99c5c3e61439f2a4b00b2d SUSE Linux 9.0: ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/i586/XFree86-libs-4.3.0.1-5… a12b2e861f114868fd70997f72536c8b patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/i586/XFree86-libs-4.3.0.1-5… c6ea49a796b316aa68dacc51ffd8eb8d source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/src/XFree86-4.3.0.1-57.src.… f53026511a470b875b0f9a63c52128d3 SUSE Linux 8.2: ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/i586/XFree86-libs-4.3.0-132… b918f14df14961cf89528a930f49d7c4 patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/i586/XFree86-libs-4.3.0-132… 9c9c268bb248f1bcf2ef899ced2d5aa4 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/src/XFree86-4.3.0-132.src.r… 9a7846ddf22d58f9f64704b3a2451640 SUSE Linux 8.1: ftp://ftp.suse.com/pub/suse/i386/update/8.1/rpm/i586/xshared-4.2.0-269.i586… d4549acb039d8bf317bc6052598764c9 patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/8.1/rpm/i586/xshared-4.2.0-269.i586… fcfc17915fdddb48ea84e4d528752edc source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/8.1/rpm/src/xf86-4.2.0-269.src.rpm 3e1d6cf799d0a8e10e2597458264812e x86-64 Platform: SUSE Linux 9.2: ftp://ftp.suse.com/pub/suse/x86_64/update/9.2/rpm/x86_64/xorg-x11-libs-32bi… e1a271567b2c784aedf3b10f60bbf8a1 patch rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.2/rpm/x86_64/xorg-x11-libs-32bi… fe95d10e1287ebbe56ba8d7a07954431 source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.2/rpm/src/baselibs-32bit-9.2-20… da697a970a5672a96016fff405f72692 SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/XFree86-libs-4.3.9… 37b2d73337bd0d70dcc092c0e15a0911 patch rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/XFree86-libs-4.3.9… d72e54995bd6468cf1ea78da81546a69 source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/src/XFree86-4.3.99.902-43… 0158b2653157f518f8dcf030927c2107 SUSE Linux 9.0: ftp://ftp.suse.com/pub/suse/x86_64/update/9.0/rpm/x86_64/XFree86-libs-4.3.0… 06a4fd1bd6eeb43fd82e18b9a255ff78 patch rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.0/rpm/x86_64/XFree86-libs-4.3.0… da96d1c51020a7de70195458b197fa3b source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.0/rpm/src/XFree86-4.3.0.1-57.sr… f369153e40af338af2fd67957db09cff ______________________________________________________________________________ 5) Pending vulnerabilities in SUSE Distributions and Workarounds: - ImageMagick This update fixes an additional problem in the EXIF handling of ImageMagick, which could lead to a buffer overflow. This could enable remote attackers feeding handcrafted images to execute code as the user handling the image. New packages are available. - clamav The clamav version shipped with SUSE Linux is too old for the new data files. The version has been upgraded to 0.80. - perl-Mime-Tools / perl-Archive-ZIP Problems in the perl-MIME-Tools and perl-Archive-ZIP packages have been found which could allow virii to pass virus scanners using those packages (like for instance clamav). Fixed packages are in testing and will be released soon. - Apache 1.3 / mod_include A potential buffer overflow and a argument sanitization problem were found in the mod_include Apache 1.3 module. These issues are tracked as CAN-2004-0940 and CAN-2004-0492 by Mitre CVE. Fixed packages are in testing and will be released soon. - Apache 2 / mod_SSL SSL Ciphersuite bypass problems were identified and fixed by the Apache team in Apache 2. This is tracked under the Mitre CVE ID CAN-2004-0885. Fixed packages are in testing and will be released soon. ______________________________________________________________________________ 6) standard appendix: authenticity verification, additional information - Package authenticity verification: SUSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SUSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We recommend against subscribing to security lists that cause the e-mail message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the file name of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SUSE in rpm packages for SUSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SUSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the top-level directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe(a)suse.com>. suse-security-announce(a)suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an email to <suse-security-announce-subscribe(a)suse.com>. For general information or the frequently asked questions (faq) send mail to: <suse-security-info(a)suse.com> or <suse-security-faq(a)suse.com> respectively. ===================================================================== SUSE's security contact is <security(a)suse.com> or <security(a)suse.de>.

15 Nov '04

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Announcement Package: samba Announcement-ID: SUSE-SA:2004:040 Date: Monday, Nov 15th 2004 18:00 MEST Affected products: 9.1, 9.2 SUSE Linux Enterprise Server 9 Novell Linux Desktop 9 Vulnerability Type: potential remote buffer overflow remote denial of service Severity (1-10): 7 SUSE default package: yes Cross References: CAN-2004-0930 CAN-2004-0882 Content of this advisory: 1) security vulnerabilities resolved: - remote buffer overflow and remote denial of service conditions in Samba 3 packages. problem description 2) solution/workaround 3) special instructions and notes 4) package location and checksums 5) pending vulnerabilities, solutions, workarounds: - bogofilter - libxml2 - clamav - various PDF viewers - mozilla /tmp issues - sharutils - phpMyAdmin - gaim - sysconfig - perl-MIME-Tools, perl-Archive-ZIP - apache / mod_include - apache2 / mod_SSL 6) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion There is a problem in the Samba file sharing service daemon, which allows a remote user to have the service consume lots of computing power and potentially crash the service by querying special wildcarded filenames. This attack can be successful if the Samba daemon is running and a remote user has access to a share (even read only). The Samba team has issued the new Samba version 3.0.8 to fix this problem, this update backports the relevant patch. This issue has been assigned the Mitre CVE ID CAN-2004-0930. Stefan Esser found a problem in the Unicode string handling in the Samba file handling which could lead to a remote heap buffer overflow and might allow remote attackers to inject code in the smbd process. This issue has been assigned the Mitre CVE ID CAN-2004-0882. We provide updated packages for both these problems. The Samba version 2 packages are not affected by this problem. 2) solution/workaround Update to the released packages. The only workaround would be not to use Samba. 3) special instructions and notes Restart the Samba daemon by entering the following command as root: rcsmb try-restart 4) package location and checksums Download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. Our maintenance customers are being notified individually. The packages are being offered for installation from the maintenance web. x86 Platform: SUSE Linux 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/samba-3.0.7-5.2.i586.r… ea47b14d991eadfc8319d248441eb6cc patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/samba-3.0.7-5.2.i586.p… 097048624c2ca75d66113c994e278bf8 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/src/samba-3.0.7-5.2.src.rpm e90db6a68fca1660ecb1f3e833034b14 SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/samba-3.0.4-1.34.3.i58… 2701bcc3f8a702828a84ca6ee6f58c47 patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/samba-3.0.4-1.34.3.i58… 2ec25548844d0741ece92ea34726b962 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/samba-3.0.4-1.34.3.src.… ce60179f36ea0005df7c69b64849b387 x86-64 Platform: SUSE Linux 9.2: ftp://ftp.suse.com/pub/suse/x86_64/update/9.2/rpm/x86_64/samba-3.0.7-5.2.x8… 13b65db6a9cd46df94cd5171d4c3b916 patch rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.2/rpm/x86_64/samba-3.0.7-5.2.x8… 0e7dd46cc7187ae3a7419dfdb8cdd1b8 source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.2/rpm/src/samba-3.0.7-5.2.src.r… e90db6a68fca1660ecb1f3e833034b14 SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/samba-3.0.4-1.34.3… 8b442529ac042ecea469972c2c85e4b5 patch rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/samba-3.0.4-1.34.3… f3c95f1940f05652393a178b6a12e226 source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/src/samba-3.0.4-1.34.3.sr… 053403aa610ea0df5b6337934e753acc ______________________________________________________________________________ 5) Pending vulnerabilities in SUSE Distributions and Workarounds: A lot of less important issues have been addressed since the last security update. To avoid spamming they are summarized here. - bogofilter The bogofilter team has notified us about a denial of service condition in bogofilter on SUSE Linux 9.2, where a non-conformant encoded word could lead to a denial of service attack against bogofilter. This issue has been assigned Mitre CVE ID CAN-2004-1007. Fixed packages are available. - libxml2 Several buffer overflows in URL handling in libxml2 were found by "infamous41md". This issue has been assigned the Mitre CVE ID CAN-2004-0989. Fixed packages are available. - clamav The clamav version shipped with SUSE Linux is too old for the new data files. The version has been upgraded to 0.80. - various xpdf based PDF viewers The SUSE QA team found several 64-bit issues in the xpdf fixes we released for CAN-2004-0888 and CAN-2004-0889. These have been fixed and updated packages have been released. - Mozilla /tmp issues The creation of several /tmp files in Mozilla and Mozilla based programs left private files with world readable permissions so that local users could read documents of other users. Packages fixing this problem have been released. - sharutils Buffer overflows and shell quoting problems have been found in the "shar" program which creates self-extracting shell archives. Fixed packages are available. - phpMyAdmin Missing parameter escapes allowed users of the phpMyAdmin frontend to execute commands as the www user on the target host. Fixed packages are available. - gaim More problems in newer versions of GAIM have been found and are tracked with the Mitre CVE ID CAN-2004-0891. Fixed packages are available. - sysconfig A permission error left the passphrase of WPA authorized wireless key world readable in SUSE Linux 9.2. Fixed packages are available. - perl-Mime-Tools / perl-Archive-ZIP Problems in the perl-MIME-Tools and perl-Archive-ZIP packages have been found which could allow virii to pass virus scanners using those packages (like for instance clamav). Fixed packages are in testing and will be released soon. - Apache 1.3 / mod_include A potential buffer overflow and a argument sanitization problem were found in the mod_include Apache 1.3 module. These issues are tracked as CAN-2004-0940 and CAN-2004-0492 by Mitre CVE. Fixed packages are in testing and will be released soon. - Apache 2 / mod_SSL SSL Ciphersuite bypass problems were identified and fixed by the Apache team in Apache 2. This is tracked under the Mitre CVE ID CAN-2004-0885. Fixed packages are in testing and will be released soon. ______________________________________________________________________________ 6) standard appendix: authenticity verification, additional information - Package authenticity verification: SUSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SUSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We recommend against subscribing to security lists that cause the e-mail message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the file name of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SUSE in rpm packages for SUSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SUSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the top-level directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe(a)suse.com>. suse-security-announce(a)suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an email to <suse-security-announce-subscribe(a)suse.com>. For general information or the frequently asked questions (faq) send mail to: <suse-security-info(a)suse.com> or <suse-security-faq(a)suse.com> respectively. ===================================================================== SUSE's security contact is <security(a)suse.com> or <security(a)suse.de>.

SUSE Security Announcement: samba (SUSE-SA:2004:040)
by Marcus Meissner 15 Nov '04

15 Nov '04

______________________________________________________________________________ SUSE Security Announcement Package: samba Announcement-ID: SUSE-SA:2004:040 Date: Monday, Nov 15th 2004 18:00 MEST Affected products: 9.1, 9.2 SUSE Linux Enterprise Server 9 Novell Linux Desktop 9 Vulnerability Type: potential remote buffer overflow remote denial of service Severity (1-10): 7 SUSE default package: yes Cross References: CAN-2004-0930 CAN-2004-0882 Content of this advisory: 1) security vulnerabilities resolved: - remote buffer overflow and remote denial of service conditions in Samba 3 packages. problem description 2) solution/workaround 3) special instructions and notes 4) package location and checksums 5) pending vulnerabilities, solutions, workarounds: - bogofilter - libxml2 - clamav - various PDF viewers - mozilla /tmp issues - sharutils - phpMyAdmin - gaim - sysconfig - perl-MIME-Tools, perl-Archive-ZIP - apache / mod_include - apache2 / mod_SSL 6) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion There is a problem in the Samba file sharing service daemon, which allows a remote user to have the service consume lots of computing power and potentially crash the service by querying special wildcarded filenames. This attack can be successful if the Samba daemon is running and a remote user has access to a share (even read only). The Samba team has issued the new Samba version 3.0.8 to fix this problem, this update backports the relevant patch. This issue has been assigned the Mitre CVE ID CAN-2004-0930. Stefan Esser found a problem in the Unicode string handling in the Samba file handling which could lead to a remote heap buffer overflow and might allow remote attackers to inject code in the smbd process. This issue has been assigned the Mitre CVE ID CAN-2004-0882. We provide updated packages for both these problems. The Samba version 2 packages are not affected by this problem. 2) solution/workaround Update to the released packages. The only workaround would be not to use Samba. 3) special instructions and notes Restart the Samba daemon by entering the following command as root: rcsmb try-restart 4) package location and checksums Download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. Our maintenance customers are being notified individually. The packages are being offered for installation from the maintenance web. x86 Platform: SUSE Linux 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/samba-3.0.7-5.2.i586.r… ea47b14d991eadfc8319d248441eb6cc patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/samba-3.0.7-5.2.i586.p… 097048624c2ca75d66113c994e278bf8 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/src/samba-3.0.7-5.2.src.rpm e90db6a68fca1660ecb1f3e833034b14 SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/samba-3.0.4-1.34.3.i58… 2701bcc3f8a702828a84ca6ee6f58c47 patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/samba-3.0.4-1.34.3.i58… 2ec25548844d0741ece92ea34726b962 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/samba-3.0.4-1.34.3.src.… ce60179f36ea0005df7c69b64849b387 x86-64 Platform: SUSE Linux 9.2: ftp://ftp.suse.com/pub/suse/x86_64/update/9.2/rpm/x86_64/samba-3.0.7-5.2.x8… 13b65db6a9cd46df94cd5171d4c3b916 patch rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.2/rpm/x86_64/samba-3.0.7-5.2.x8… 0e7dd46cc7187ae3a7419dfdb8cdd1b8 source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.2/rpm/src/samba-3.0.7-5.2.src.r… e90db6a68fca1660ecb1f3e833034b14 SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/samba-3.0.4-1.34.3… 8b442529ac042ecea469972c2c85e4b5 patch rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/samba-3.0.4-1.34.3… f3c95f1940f05652393a178b6a12e226 source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/src/samba-3.0.4-1.34.3.sr… 053403aa610ea0df5b6337934e753acc ______________________________________________________________________________ 5) Pending vulnerabilities in SUSE Distributions and Workarounds: A lot of less important issues have been addressed since the last security update. To avoid spamming they are summarized here. - bogofilter The bogofilter team has notified us about a denial of service condition in bogofilter on SUSE Linux 9.2, where a non-conformant encoded word could lead to a denial of service attack against bogofilter. This issue has been assigned Mitre CVE ID CAN-2004-1007. Fixed packages are available. - libxml2 Several buffer overflows in URL handling in libxml2 were found by "infamous41md". This issue has been assigned the Mitre CVE ID CAN-2004-0989. Fixed packages are available. - clamav The clamav version shipped with SUSE Linux is too old for the new data files. The version has been upgraded to 0.80. - various xpdf based PDF viewers The SUSE QA team found several 64-bit issues in the xpdf fixes we released for CAN-2004-0888 and CAN-2004-0889. These have been fixed and updated packages have been released. - Mozilla /tmp issues The creation of several /tmp files in Mozilla and Mozilla based programs left private files with world readable permissions so that local users could read documents of other users. Packages fixing this problem have been released. - sharutils Buffer overflows and shell quoting problems have been found in the "shar" program which creates self-extracting shell archives. Fixed packages are available. - phpMyAdmin Missing parameter escapes allowed users of the phpMyAdmin frontend to execute commands as the www user on the target host. Fixed packages are available. - gaim More problems in newer versions of GAIM have been found and are tracked with the Mitre CVE ID CAN-2004-0891. Fixed packages are available. - sysconfig A permission error left the passphrase of WPA authorized wireless key world readable in SUSE Linux 9.2. Fixed packages are available. - perl-Mime-Tools / perl-Archive-ZIP Problems in the perl-MIME-Tools and perl-Archive-ZIP packages have been found which could allow virii to pass virus scanners using those packages (like for instance clamav). Fixed packages are in testing and will be released soon. - Apache 1.3 / mod_include A potential buffer overflow and a argument sanitization problem were found in the mod_include Apache 1.3 module. These issues are tracked as CAN-2004-0940 and CAN-2004-0492 by Mitre CVE. Fixed packages are in testing and will be released soon. - Apache 2 / mod_SSL SSL Ciphersuite bypass problems were identified and fixed by the Apache team in Apache 2. This is tracked under the Mitre CVE ID CAN-2004-0885. Fixed packages are in testing and will be released soon. ______________________________________________________________________________ 6) standard appendix: authenticity verification, additional information - Package authenticity verification: SUSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SUSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We recommend against subscribing to security lists that cause the e-mail message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the file name of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SUSE in rpm packages for SUSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SUSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the top-level directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe(a)suse.com>. suse-security-announce(a)suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an email to <suse-security-announce-subscribe(a)suse.com>. For general information or the frequently asked questions (faq) send mail to: <suse-security-info(a)suse.com> or <suse-security-faq(a)suse.com> respectively. ===================================================================== SUSE's security contact is <security(a)suse.com> or <security(a)suse.de>. The <security(a)suse.de> public key is listed below. ===================================================================== ______________________________________________________________________________ The information in this advisory may be distributed or reproduced, provided that the advisory is not modified in any way.
