-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Announcement Package: lftp Announcement-ID: SuSE-SA:2003:051 Date: Monday, Dec 15th 2003 14:30 MET Affected products: 8.2, 9.0 remote system compromise Severity (1-10): 3 SUSE default package: no Cross References: Content of this advisory: 1) security vulnerability resolved: - local buffer overflow problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - mc - mod_gzip - freeradius - tripwire - cvs - irssi - atftp 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The the flexible and powerful FTP command-line client lftp is vulnerable to two remote buffer overflows. When using lftp via HTTP or HTTPS to execute commands like 'ls' or 'rels' specially prepared directories on the server can trigger a buffer overflow in the HTTP handling functions of lftp to possibly execute arbitrary code on the client-side. Please note, to exploit these bugs an attacker has to control the server- side of the context and the attacker will only gain access to the account of the user that is executing lftp. There is no temporary workaround known. Please 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 to install from the maintenance web. Intel i386 Platform: SuSE-9.0: ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/i586/lftp-2.6.6-71.i586.rpm 2e5aee46868b5b19c26a8559927e8663 patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/i586/lftp-2.6.6-71.i586.pat… 0468cf8f2b2b4c18a854f51ef63470b7 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/src/lftp-2.6.6-71.src.rpm a32eee3ff4eeb322d44f04b9f8ff4c9c SuSE-8.2: ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/i586/lftp-2.6.4-44.i586.rpm df0d7c059cd3bb4fe47c927849fd9a5e patch rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/i586/lftp-2.6.4-44.i586.pat… eb9d6aedc25d3e2d25b63999526ee1bd source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/src/lftp-2.6.4-44.src.rpm 63695b02bf520b02f93ec73078d6e4d8 ______________________________________________________________________________ 2) Pending vulnerabilities in SUSE Distributions and Workarounds: - mc By using a special combination of links in archive-files it is possible to execute arbitrary commands while mc tries to open it in its VFS. The packages are currently tested and will be release as soon as possible. - mod_gzip The apache module mod_gzip is vulnerable to remote code execution while running in debug-mode. We do not ship this module in debug-mode but future versions will include the fix. Additionally the mod_gzip code was audited to fix more possible security related bugs. - freeradius Two vulnerabilities were found in the FreeRADIUS package. The remote denial-of-service attack bug was fixed and new packages will be released as soon as testing was successfully finished. The other bug is a remote buffer overflow in the module rlm_smb. We do not ship this module and will fix it for future releases. - tripwire Tripwire is a file integrity checker. The tripwire version on SuSE Linux 8.2 and 9.0 do crash when a requested file does not exists. New packages will be available soon. - cvs The cvs server-side can be tricked to create files in the root filesystem of the server by requesting malformed modules. The permissions on the root filesystem normally prevent this malfunction. New packages will be available soon. - irssi Under special circumstances the the irc-client irssi can be crashed remotely by other irc-clients. A fix will be available soon. - atftp A buffer overflow vulnerability discovered by Rick Patel has been fixed in the atftpd (trivial file transfer protocol, UDP oriented) daemon, contained in the atftp package. Update packages for the affected SUSE Linux distributions 8.1 and 8.2 have been published on our ftp server today. We explicitly thank Dirk Mueller, KDE developer, for notifying SUSE Security about the pending treatment of this incident. ______________________________________________________________________________ 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 disrecommend to subscribe to security lists which cause the email 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 filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an un-installed 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.

Discontinued SuSE Linux Distributions
by Roman Drahtmueller 04 Dec '03

04 Dec '03

-----BEGIN PGP SIGNED MESSAGE----- Thu Dec 4 18:00:00 MET 2003 Dear suse-security-announce subscribers and SUSE LINUX users, having provided security-relevant fixes for version 7.3 of our home user product, SuSE Linux, for two years, we would like to inform you that SuSE Linux 7.3 will be discontinued for all architectures. Vulnerabilities found after December 15th 2003 will not be fixed any more for SuSE Linux 7.3. By consequence, the SuSE Linux 7.3 distribution directories on our ftp server ftp.suse.com will be moved to the /pub/suse/discontinued/ directory tree structure; the 7.3 directories in the update trees will follow later in January 2004. The discontinuation of SuSE Linux 7.3 enables us to focus on the SUSE LINUX distributions of a newer release date to ensure that our customers can continuously take advantage of the quality that they are used to with SUSE LINUX products. This announcement holds true for SuSE Linux 7.3 only. As usual, SUSE will continue to provide update packages for the following home users distributions: SuSE Linux 8.0 SuSE Linux 8.1 SuSE Linux 8.2 and SUSE LINUX 9.0 for a two-year period after the release of the respective distribution. Please note that the maintenance cycles of SUSE LINUX Enterprise Server products and products based on the SUSE LINUX Enterprise Server operating system are not affected by this announcement. To learn more about SUSE LINUX business products, please visit http://www.suse.com/us/business/products/. If you have any questions regarding this announcement, please do not hesitate to contact SUSE security at <security(a)suse.de>.

SUSE Security Announcement: rsync (SuSE-SA:2003:050)

In most private networks the rsync client tool is used via SSH to fulfill his tasks. In an open environment rsync is run in server mode accepting connections from many untrusted hosts with, but mostly without, authentication. The rsync server drops its root privileges soon after it was started and per default creates a chroot environment. Due to insufficient integer/bounds checking in the server code a heap overflow can be triggered remotely to execute arbitrary code. This code does not get executed as root and access is limited to the chroot environment. The chroot environment maybe broken afterwards by abusing further holes in system software or holes in the chroot setup. Your are not vulnerable as long as you do not use rsync in server mode or you use authentication to access the rsync server. As a temporary workaround you can disable access to your rsync server for untrusted parties, enable authentication or switch back to rsync via SSH. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement.

Vulnerabilities found after December 15th 2003 will not be fixed any more for SuSE Linux 7.3. Directory structures referring to the SuSE Linux 7.3 release will be moved to the discontinued/ tree on our main ftp server ftp.suse.com the distribution directories first, followed by the update/ directory tree in January 2004. Please note that our SuSE Linux Enterprise Server family products have a much longer support period. These products are not concerned by this announcement. - KDE New KDE packages are currently being tested. These packages fixes several vulnerabilities: + remote root compromise (CAN-2003-0690) + weak cookies (CAN-2003-0692) + SSL man-in-the-middle attack + information leak through HTML-referrer (CAN-2003-0459) + wrong file permissions of config files The packages will be release as soon as testing is finished. - mc By using a special combination of links in archive-files it is possible to execute arbitrary commands while mc tries to open it in its VFS. The packages are currently tested and will be release as soon as possible. - apache1/2 The widely used HTTP server apache has several security vulnerabilities: - locally exploitable buffer overflow in the regular expression code. The attacker must be able to modify .htaccess or httpd.conf. (affects: mod_alias and mod_rewrite) - under some circumstances mod_cgid will output its data to the wrong client (affects: apache2) Update packages are available on our FTP servers. - freeradius Two vulnerabilities were found in the FreeRADIUS package. The remote denial-of-service attack bug was fixed and new packages will be released as soon as testing was successfully finished. The other bug is a remote buffer overflow in the module rlm_smb. We do not ship this module and will fix it for future releases. - screen A buffer overflow in screen was reported. Since SuSE Linux 8.0 we do not ship screen with the s-bit anymore. An update package will be released for 7.3 as soon as possible. - mod_gzip The apache module mod_gzip is vulnerable to remote code execution while running in debug-mode. We do not ship this module in debug-mode but future versions will include the fix. Additionally the mod_gzip code was audited to fix more possible security related bugs. - unace The tool unace for handling the archive format ACE is vulnerable to a buffer overflow that can be triggered with long file-names as command line argument. This only affects unace version 2.5. Unfortunately this tool is provided closed source only from the author. Therefore we are unable to check for other bugs or look at the patch. Update packages are available from our FTP servers. ______________________________________________________________________________ 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 disrecommend to subscribe to security lists which cause the email 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 filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an un-installed 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.

SuSE Security Announcement: Kernel brk() vulnerability (SuSE-SA:2003:049)
by Olaf Kirch 04 Dec '03

04 Dec '03

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Announcement Package: Linux Kernel Announcement-ID: SuSE-SA:2003:049 Date: Thursday, December 4th 2003 15:30 MET Affected products: 7.3, 8.0, 8.1, 8.2, 9.0 SuSE Linux Enterprise Server 7, SuSE Linux Database Server, SuSE eMail Server III, 3.1 SuSE Linux Firewall on CD/Admin host SuSE Linux Office Server SuSE Linux Desktop 1.0 SuSE Linux School Server Vulnerability Type: local root exploit Severity (1-10): 8 SUSE default package: yes Cross References: CAN-2003-0961 Content of this advisory: 1) security vulnerability resolved: - Linux kernel brk() integer overflow problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - KDE - mc - apache1/2 - freeradius - screen - mod_gzip - unace 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information This security update fixes a serious vulnerability in the Linux kernel. A missing bounds check in the brk() system call allowed processes to request memory beyond the maximum size allowed for tasks, causing kernel memory to be mapped into the process' address space. This allowed local attackers to obtain super user privileges. An exploit for this vulnerability is circulating in the wild, and has been used to compromise OpenSource development servers. There is no temporary workaround for this bug. This update also fixes several other security issues in the kernel - race condition with files opened via O_DIRECT which could be exploited to read disk blocks randomly. This could include blocks of previously deleted files with sensitive content. - don't allow users to send signals to kmod - when reading the RTC, don't leak kernel stack data to user space SPECIAL INSTALL INSTRUCTIONS: ============================== The following paragraphs will guide you through the installation process in a step-by-step fashion. The character sequence "****" marks the beginning of a new paragraph. In some cases, you decide if the paragraph is needed for you or not. Please read through all of the steps down to the end. All of the commands that need to be executed are required to be run as the superuser (root). Each step relies on the steps before to complete successfully. **** Step 1: Determine the needed kernel type Please use the following command to find the kernel type that is installed on your system: rpm -qf /boot/vmlinuz The following options are possible (disregarding the version and build number following the name, separated by the "-" character): k_deflt # default kernel, good for most systems. k_i386 # kernel for older processors and chipsets k_athlon # kernel made specifically for AMD Athlon(tm) family processors k_psmp # kernel for Pentium-I dual processor systems k_smp # kernel for SMP systems (Pentium-II and above) **** Step 2: Download the package for your system Please download the kernel RPM package for your distribution with the name starting as indicated by Step 1. The list of all kernel rpm packages is appended below. Note: The kernel-source package does not contain any binary kernel in bootable form. Instead, it contains the sources that the binary kernel rpm packages are made from. It can be used by administrators who have decided to build their own kernel. Since the kernel-source.rpm is an installable (compiled) package that contains sources for the linux kernel, it is not the source RPM for the kernel RPM binary packages. The kernel RPM binary packages for the distributions can be found at these locations below ftp://ftp.suse.com/pub/suse/i386/update/. 7.3/kernel/2.4.18-20031204 8.0/kernel/2.4.18-20031204 8.1/rpm/i586 8.2/rpm/i586 9.0/rpm/i586 After downloading the kernel RPM package for your system, you should verify the authenticity of the kernel rpm package using the methods as listed in section 3) of each SUSE Security Announcement. **** Step 3: Installing your kernel rpm package Install the rpm package that you have downloaded in Steps 3 or 4 with the command rpm -Uhv --nodeps --force <K_FILE.RPM> where <K_FILE.RPM> is the name of the rpm package that you downloaded. Warning: After performing this step, your system will likely not be able to boot if the following steps have not been fully applied. If you run SUSE LINUX 8.1 and haven't applied the previous kernel update (SUSE-SA:2003:034), AND use the freeswan package, you also need to update the freeswan rpm as a dependency as offered by YOU (Yast Online Update). The package can be downloaded from ftp://ftp.suse.com/pub/suse/i386/update/8.1/rpm/i586/ **** Step 4: configuring and creating the initrd The initrd is a ramdisk that is being loaded into the memory of your system together with the kernel boot image by the bootloader. The kernel uses the content of this ramdisk to execute commands that must be run before the kernel can mount its actual root filesystem. It is usually used to initialize scsi drivers or NIC drivers for diskless operation. The variable INITRD_MODULES (set in the files /etc/rc.config up to 7.3) or /etc/sysconfig/kernel (after and including 8.0)) determines which kernel modules will be loaded in the initrd before the kernel has mounted its actual root filesystem. The variable should contain your scsi adapter (if any) or filesystem driver modules. With the installation of the new kernel, the initrd has to be re-packed with the update kernel modules. Please run the command mk_initrd as root to create a new init rmadisk (initrd) for your system. On SuSE Linux 8.1 and later, this is done automatically when the RPM is installed. **** Step 5: bootloader If you have a 7.x system, you must now run the command lilo as root to initialize the lilo bootloader for your system. Then proceed to the next step. If you run a SUSE LINUX 8.x or a SLES8 system, there are two options: Depending on your software configuration, you have the lilo bootloader or the grub bootloader installed and initialized on your system. The grub bootloader does not require any further actions to be performed after the new kernel images have been moved in place by the rpm Update command. If you have a lilo bootloader installed and initialized, then the lilo program must be run as root. Use the command grep LOADER_TYPE /etc/sysconfig/bootloader to find out which boot loader is configured. If it is lilo, then you must run the lilo command as root. If grub is listed, then your system does not require any bootloader initialization. Warning: An improperly installed bootloader may render your system unbootable. **** Step 6: reboot If all of the steps above have been successfully applied to your system, then the new kernel including the kernel modules and the initrd should be ready to boot. The system needs to be rebooted for the changes to become active. Please make sure that all steps are complete, then reboot using the command shutdown -r now or init 6 Your system should now shut down and reboot with the new kernel.

______________________________________________________________________________ 2) Pending vulnerabilities in SUSE Distributions and Workarounds: - KDE New KDE packages are currently being tested. These packages fixes several vulnerabilities: + remote root compromise (CAN-2003-0690) + weak cookies (CAN-2003-0692) + SSL man-in-the-middle attack + information leak through HTML-referrer (CAN-2003-0459) + wrong file permissions of config files The packages will be release as soon as testing is finished. - mc By using a special combination of links in archive-files it is possible to execute arbitrary commands while mc tries to open it in its VFS. The packages are currently tested and will be release as soon as possible. - apache1/2 The widely used HTTP server apache has several security vulnerabilities: - locally exploitable buffer overflow in the regular expression code. The attacker must be able to modify .htaccess or httpd.conf. (affects: mod_alias and mod_rewrite) - under some circumstances mod_cgid will output its data to the wrong client (affects: apache2) Update packages are available on our FTP servers. - freeradius Two vulnerabilities were found in the FreeRADIUS package. The remote denial-of-service attack bug was fixed and new packages will be released as soon as testing was successfully finished. The other bug is a remote buffer overflow in the module rlm_smb. We do not ship this module and will fix it for future releases. - screen A buffer overflow in screen was reported. Since SuSE Linux 8.0 we do not ship screen with the s-bit anymore. An update package will be released for 7.3 as soon as possible. - mod_gzip The apache module mod_gzip is vulnerable to remote code execution while running in debug-mode. We do not ship this module in debug-mode but future versions will include the fix. - unace The tool unace for handling the archive format ACE is vulnerable to a buffer overflow that can be triggered with long file-names as command line argument. This only affects unace version 2.5. Unfortunately this tool is provided closed source only from the author. Therefore we are unable to check for other bugs or look at the patch. Update packages are available from our FTP servers. ______________________________________________________________________________ 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 disrecommend to subscribe to security lists which cause the email 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 filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an un-installed 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: gpg (SuSE-SA:2003:048)

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Announcement Package: gpg Announcement-ID: SuSE-SA:2003:048 Date: Wednesday, December 3rd 2003 15:15 MET Affected products: 7.3, 8.0, 8.1, 8.2, 9.0 SuSE Linux Enterprise Server 7, 8 SuSE Linux Database Server, SuSE eMail Server III, 3.1 SuSE Linux Firewall on CD/Admin host SuSE Linux Connectivity Server SuSE Linux Office Server SuSE Linux Desktop 1.0 SuSE Linux School Server SuSE Linux Standard Server 8 Vulnerability Type: cryptographic compromise, remote cmd execution Severity (1-10): 5 SUSE default package: yes Cross References: CAN-2003-0971 http://www.gnupg.org/ http://lists.gnupg.org/pipermail/gnupg-announce/2003q4/000276.html Content of this advisory: 1) security vulnerability resolved: gpg problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - kernel 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The gnupg (the SUSE package is named gpg) package is the most widely used software for cryptographic encryption/decryption of data. Two independent errors have been found in gpg (GnuPG) packages as shipped with SUSE products: A) A format string error in the client code that does key retrieval from a (public) key server B) A cryptographic error in gpg that results in a compromise of a cryptographic keypair if ElGamal signing keys have been used for generating the key. A) There exists a format string error in thhe client code for key retrieval from a keyserver. gpg-1.2.x version packages are affected by this vulnerability. The format string error can be used by an attacker performing a man-in-the-middle-attack between you and your keyserver, or by a compromised keyserver. The result is a crash of gpg or a potential execution of arbitrary code provided by the attacker, if the keyserver is used for key retrieval at the time of the attack. B) Werner Koch, the author of the gpg package, has publicly announced a weakness in gpg that has been reported to him by Phong Nguyen: ElGamal signing keys can be attacked within seconds to reveal the private key of the keypair. It is strongly advised that ElGamal signing keys should be revoked immediately. Only ElGamal keys are affected, other types are not vulnerable. To find out if you are using an ElGamal signing key, list your public keys using the command gpg --list-keys your_keyid Example: $ gpg --list-keys build(a)suse.de pub 1024D/9C800ACA 2000-10-19 SuSE Package Signing Key <build(a)suse.de> sub 2048g/8495160C 2000-10-19 [expires: 2006-02-12] $ If your key lists a capital "G" after the key's length (like in pub 1536G/...), then your key is vulnerable. A small letter "g" after the key length does NOT indicate any problem. ElGamal keys can be used for primary keys as well as for subkeys. In the case where only a subkey is an ElGamal key, it is sufficient to revoke this specific subkey. To revoke a key, generate a revocation certificate using the following command: gpg --gen-revoke your_keyid > revocation_certificate.pgp Then, the revokation certificate must be imported into your keyring: gpg --import < revocation_certificate.pgp As your last action, send the key with its revocation certificate to the keyservers that know your key: gpg --keyserver wwwkeys.eu.pgp.net --send-keys your_keyid ElGamal keys can only be generated by gpg if a special option (--expert) has been used to reveal "expert" options, and if a warning has been ignored after your choice to use ElGamal keys. Such keys are rare (Werner Koch reports 848 primary ElGamal signing keys and 324 vulnerable subkeys on the keyservers.). Therefore, we expect that only experienced users of gpg may be vulnerable to the ElGamal signing key error. UPDATES: The nature of the ElGamal error implies that a possible compromise was made possible with the generation of the key in the past already. There is no way that an update package can prevent the compromise. However, the update packages that we provide prevent the use of ElGamal signing keys for key generation once the packages are installed. SUSE Linux 8.1 and before contain a gpg package of version 1.0.x (vulnerable to the ElGamal signing key bug only), a version of 1.2.x has been shipped with SUSE Linux 8.2 and 9.0 (vulnerable to both errors). We provide update packages that fix both vulnerabilities, meaning that only the packages affected by both vulnerabilities are being updated. For this reason, there are only update packages for SuSE Linux 8.2 and SUSE LINUX 9.0 available for download. Important Note: A proper installation of the gpg update package is critical for future updates on your system. The gpg program is being used by YaST Online Update (YOU) to verify the authenticity of your update package. A failure of a signature verification will result in a failure of the installation of update packages. Please 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 to install from the maintenance web.

We are in the process of testing the update packages for all of our products. The packages are expected to be released within hours and are being published as they are ready. Please follow the guidelines in the announcement about the kernel that follows this announcement. ______________________________________________________________________________ 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 disrecommend to subscribe to security lists which cause the email 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 filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an un-installed 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.
