-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: sendmail Announcement-ID: SuSE-SA:2001:028 Date: Thursday, Aug 23rd 2001 18:10 MEST Affected SuSE versions: 7.0, 7.1, 7.2 Vulnerability Type: local root compromise Severity (1-10): 5 SuSE default package: yes Other affected systems: systems using the sendmail package Content of this advisory: 1) security vulnerability resolved: sendmail problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information Cade Cairns of Securityfocus discovered a vulnerability in the sendmail program, the widely spread MTA used in Unix- and Unix-like systems. A local user can write arbitrary data to the process memory, resulting in user-controlled code to be executed as user root. Please note that this is a _local_ vulnerability: Local shell access is needed for the attacker to be able to take advantage of this error. The /usr/sbin/sendmail program is installed set-uid root in most installations. This special privilege is needed for the sendmail program to operate properly. The attack pattern involves running sendmail to make use of the setuid-bit. Please note that this is the first sendmail security problem since 1997. In this case, the vulnerability can be classified as a commandline processing bug while running with extended (root) privilege. The error itself is a result of a comparison between a signed and an unsigned integer when checking user-supplied data from the sendmail command line: A high unsigned value is being considered a negative signed value. A subsequent comparison is being evaluated the wrong way. These errors are expected to make up a new class of vulnerabilities for programs written in C in the near future. The supported SuSE Linux distributions 6.3 and 6.4 use a sendmail of version 8.9.3. According to Sendmail Inc., this version is not affected by this signedness bug. The SuSE Linux distributions 7.0, 7.1 and 7.2 use sendmail version 8.11.x. All 7.x distributions are affected by the problem. SuSE provides update packages for the affected distributions. Please download the update package for your distribution and use the command 'rpm -Uhv file.rpm' to apply the update. It is recommended to stop the running sendmail process(es) before applying the update. Use the command 'rcsendmail stop' to do this, and 'rcsendmail start' to restart the service after the update has been applied. Since the update packages only fix the security problem from this announcement, no reconfiguration should be necessary. SPECIAL INSTALL INSTRUCTIONS: The sendmail package needs one out of two commands to be executed after package installation. Use the commands SuSEconfig or, alternatively (if you have disabled SuSEconfig in /etc/rc.config), chkstat -set /etc/permissions.d/sendmail to set the permissions of the sendmail package files correctly. Without these permission changes, the /usr/sbin/sendmail program will not operate properly. (Side note: All of the commands above have to be run as root!) i386 Intel Platform: SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n1/sendmail-8.11.3-68.i386.rpm edffc3231b74858c218e540ffb37740a SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/sec2/sendmail-tls-8.11.3-72.i38… 6a99faaaf394ab7b6dd22d9d81fb221b source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/sendmail-8.11.3-68.src.rpm e914fef1f5fb1c65bb7b52383f9832db SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n1/sendmail-8.11.2-34.i386.rpm 6cf817fe71a07fc58d4b201df01291b5 SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/sec2/sendmail-tls-8.11.2-29.i38… d96f3e373f7c628d5792a2567e02e4c3 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/sendmail-8.11.2-34.src.rpm 35c53244eafc645d4d9218d95c4f6d71 SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/n1/sendmail-8.11.0-5.i386.rpm 29250e9986dfd22c7bdf637ac5dcc646 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/sendmail-8.11.0-5.src.rpm 13153a10c4223450119d2bd57178b8d4 Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/n1/sendmail-8.11.2-17.sparc.rpm 08b83155a16e86bf0b41596b66115443 SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/sec2/sendmail-tls-8.11.2-16.sp… 3d0b567682df307f13e552b4f85b798b source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/sendmail-8.11.2-17.src.rpm a67beda92d8cbae62e8d69b263970108 SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/n1/sendmail-8.11.0-3.sparc.rpm 17c9c5ce0814ee9821d7646d7ea399de source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/sendmail-8.11.0-3.src.rpm d737219fb680f990d52faff49d53a48f AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/n1/sendmail-8.11.2-19.alpha.rpm 6b7729f0c2b5dde8abb55102310bc039 SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/sec2/sendmail-tls-8.11.2-21.alph… c49dd3298689e2247a5228dfb3022949 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/sendmail-8.11.2-19.src.rpm bfa6c0c95baa236cebcf501e4efdb0e9 PPC Power PC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/n1/sendmail-8.11.2-23.ppc.rpm 1ad2a5891a03cffd33baab76d0aed4f9 SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/sec2/sendmail-tls-8.11.2-21.ppc.… b1181efdc649f005bc4a2b3fce08d164 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/sendmail-8.11.2-23.src.rpm 4caafc40ff5332dab46cc60e3f2a85fb SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/n1/sendmail-8.11.0-33.ppc.rpm 27d5ac4d6d809a1ae88cf6a3fefe1d64 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/sendmail-8.11.0-33.src.rpm f6600b2aac4d3f8356494a3d047c72f9 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions, Workarounds and misc: - ftp server Our ftp server ftp.suse.com has been reorganized. The changes in particular are: * The discontinued distributions (SuSE Linux before (and including) 6.2) have moved to an own tree: /pub/suse/discontinued/<arch>. The tree there is built exactly like the tree for the currently supported distributions (6.3 and up). This change has been made to keep users from automatically applying updates against old problems that have been superceded by newer updates which are not available for the discontinued distributions. * The /pub/suse/<arch>/{KDE,KDE2,GNOME,X} directories have been moved to an own tree: /pub/suse/<arch>/supplementary/. The KDE directory has become famous in the KDE scene because it contains the latest KDE packages compiled for a SuSE distribution. This has been done to point out that the packages in this directory have been built for the respective distribution, they are tested ok, but since these packages have never been part of the distribution they are built for, there is no support for them; the packages are provided as-is. * During the next days, all packages under the /pub/suse/<arch>/update/ tree will be gpg-signed with the build(a)suse.de DSA key (see section 3 of this announcement). Currently, most of the formerly existing directories that have been moved are now still visible through a symlink, pointing at a directory with a README. The directory paths to the update packages for the supported distributions have _not_ changed. We kindly request mirror admins to adopt the changes to their trees. If you run a publically accessible mirror of ftp.suse.com, you are invited to send a mail to ftpadmin(a)suse.com so that you are being notified of such changes in advance. - in.telnetd A buffer overflow vulnerability has been found in the in.telnetd telned daemon, a service that is enabled by default in all SuSE Linux distributions. The vulnerability may allow a remote attacker to gain root access to your system. Many unix- and unix-like operating systems are affected by this or a similar problem. There are update packages for the SuSE Linux distributions 7.1 and 7.2 on our ftp server. The packages for the 7.1 distribution are called "nkitserv", for the 7.2 distributions, the name is telnet-server. For completeness, we also provide the other packages that are made from the same source rpm. Since these packages do not fix a security problem, there is no reason to list them here. We are working on a suitable solution for the 7.0 and 6.x distributions, while it has turned out that a fix for these distributions is non-trivial because a different code base has been used for these packages. telnet is an unencrypted protocol that offers many attack possibilities. If at all possible, please deactivate your telnetd by commenting it out in /etc/inetd.conf (killall -HUP inetd afterwards to make inetd reload its configuration file!). We recommend to use one of the two ssh implementations on our distributions as a substitute of the telnet protocol. Clients are available on the internet for most platforms and operating systems. An announcement will be released soon that addresses the problem in in.telnetd. - Yesterday (Wednesday, 20010822) Bob Vickers (Dept of Computer Science, University of London) reported a locally exploitable security hole in the script /etc/init.d/boot. The critical function of the script is supposed to remove files from the defined temporary directories of the system as specified in /etc/rc.config (TMP_DIRS_TO_CLEAR in /etc/rc.config) if $CLEAR_TMP_DIRS_AT_BOOTUP (also from /etc/rc.config) is set to "yes". Unfortunately, the script does not take into account that directories can contain newlines and other non-standard characters. By consequence, the script can be tricked to removing files elsewhere. This bug is present in the SuSE Linux 7.2 version only, available for the Intel i386 platform. The feature responsible for this bug is disabled by default in a SuSE Linux 7.2 installation and must be manually activated for the bug to impose any risk. We have fixed the problem in an update package that is available at ftp://ftp.suse.com/pub/suse/i386/update/7.2/a1/aaa_base-2001.8.23-0.i386.rpm Please download and install the update package using the command rpm -Uhv aaa_base-2001.8.23-0.i386.rpm Disregard the messages on standard output if you have the gpg package installed: The postinstall script adds the DSA key build(a)suse.de to root's gpg public keyring if this hasn't been done already. This key is also listed below. A source rpm is also available at the usual location. We will not issue a dedicated security announcement for this problem. We thank Bob Vickers for reporting the problem to security(a)suse.de. - openssl A weakness was found in the PRNG (Pseudo Random Number Generator) of the openssl package. As far as we could determine, the bug has no effect on the packages that are compiled against a library from the openssl package. We will however provide update packages that fix the found problems. Since openssl packages are not (backwards-) compatible to any other newer version, we have to fix the package for each distribution seperately. This takes some time. A special announce- ment will be issued as soon as all packages are available. - more announcements are in our queue. Please keep watching activity on the suse-security-announce(a)suse.com mailinglist (more information below). ______________________________________________________________________________ 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 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 toplevel 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.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: sdb Announcement-ID: SuSE-SA:2001:027 Date: Monday, August 20th 2001 10:00 MEST Affected SuSE versions: [6.0, 6.1, 6.2,] 6.3, 6.4, 7.0, 7.1, 7.2 Vulnerability Type: local (maybe remote) privilege escalation Severity (1-10): 4 SuSE default package: yes Other affected systems: no Content of this advisory: 1) security vulnerability resolved: sdbsearch.cgi problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information Sdbsearch.cgi is Perl script which is part of the sdb package of SuSE Linux was found vulnerable by using untrustworthy client input (HTTP_REFERER). By exploiting this trust an attacker could force the sdbsearch.cgi script to open a malicious keylist file which includes keywords and filenames. By replacing the filename in the keylist file with the Perl pipe followed by arbitrary shell commands the sdbsearch.cgi would execute these commands when trying to open these 'filenames'. Note, that the attacker needs local access to the machine to store the keylist file on the server running sdbsearch.cgi. Misconfigured ftp accounts, trojan tar balls or RPM files could also be used.

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 advise against subscribing to 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 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 toplevel 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: fetchmail (SuSE-SA:2001:026)

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: fetchmail Announcement-ID: SuSE-SA:2001:026 Date: Thursday, August 16th 2001 11:30 MEST Affected SuSE versions: [6.0, 6.1, 6.2,] 6.3, 6.4, 7.0, 7.1, 7.2 Vulnerability Type: remote privilege escalation Severity (1-10): 6 SuSE default package: yes Other affected systems: yes Content of this advisory: 1) security vulnerability resolved: fetchmail problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information Fetchmail is a tool for retrieving and forwarding mail. Two vulnerabilities in the code of fetchmail were found in the last weeks. 1.) By sending a header with a large "To:" line a buffer overflow will be triggered in the header parsing code. 2.) By impersonating a pop3 or imap server by using DNS spoofing or getting control over the pop3/imap server an attacker could trigger a buffer overflow in the pop3 and imap code of fetchmail. All the attacker has to do is to fake a LIST response message and providing two integers. One will used as index for a stack array and the other one is the value written to this index. Both vulnerabilities could be used to get remote access to the system with the privilege of the user running fetchmail. A temporary fix is not possible, so we suggest to install the new RPM on your system. i386 Intel Platform: SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n1/fetchmail-5.8.0-48.i386.rpm 995660f54f997eb33120c6dcdab5ca73 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/fetchmail-5.8.0-48.src.rpm 6466071439f694d89d011c35265de909 SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n1/fetchmail-5.6.5-27.i386.rpm a6185bbbd1cdeb6f4b5a7afbe8efcd31 SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n2/fetchmailconf-5.6.5-0.i386.r… 4ed63ae1652db9037c56e8a6bbf95da2 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/fetchmail-5.6.5-27.src.rpm 27aed0c7fbfb882dce9451a1c673908d SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/n1/fetchml-5.4.0-3.i386.rpm b2aec10ba865e37bef95a32f8adfa8d2 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/fetchml-5.4.0-3.src.rpm 8a133db913032e2ea04517e0d86dde5c SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/n1/fetchml-5.3.0-3.i386.rpm d8c0aed277da334a5be9d7241f2d3fc3 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/fetchml-5.3.0-3.src.rpm 732deaa4ba6e181d15c8dbabff5e309f SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/n1/fetchml-5.1.2-7.i386.rpm d0e91680594f84f161f8dfee95125e0a source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/fetchml-5.1.2-7.src.rpm cac94bd2373d75dad6c91d66583eadfb Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/n1/fetchmail-5.6.5-12.sparc.rpm 4d7dcbf03a030ece4dd50acd3b330ad3 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/fetchmail-5.6.5-12.src.rpm 9d245f4358da492133e5a735497dbf2b SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/n1/fetchml-5.4.0-3.sparc.rpm 07462524836665fb3ad8da365b948f5f source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/fetchml-5.4.0-3.src.rpm bb2438d4e03b01415d675c2d05e3c847 AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/n1/fetchmail-5.6.5-16.alpha.rpm 0a4503aadd5981e9a4c2bc57a46eb9b9 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/fetchmail-5.6.5-16.src.rpm a8c6425a9f15b04ff27a4f0636e65f93 SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/n1/fetchml-5.4.0-3.alpha.rpm 851a72a94dc9aa152fff3f9dfd30aeb5 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/fetchml-5.4.0-3.src.rpm e876b48882702c6c45e01326f85a610a SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/n1/fetchml-5.3.0-3.alpha.rpm e44e632813710d4eb3b778414733631e source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/fetchml-5.3.0-3.src.rpm 27908e4fe9995dd86054533d17e85f5b SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/n1/fetchml-5.1.2-4.alpha.rpm 0751d23ccdfd860409cb592b84c203e4 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/fetchml-5.1.2-4.src.rpm ac0a757562c01bf84780fd81e04a7784 PPC PowerPC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/n1/fetchmail-5.6.5-16.ppc.rpm f84f2b9f669e3ba65d42ddac78b9f49c source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/fetchmail-5.6.5-16.src.rpm 999b7fcfb1799ae98d5a2ffaf103f9a7 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/n1/fetchml-5.4.0-3.ppc.rpm 55a46529b8f9cae39cd3a3d06728e300 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/fetchml-5.4.0-3.src.rpm b3ecbc340fb46e5c6501f34184fa69fd SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/n1/fetchml-5.3.0-3.ppc.rpm d3bf46ca935d696b1a45ff1b3c820840 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/fetchml-5.3.0-3.src.rpm 6dbd73a017fd2915c9197860f47a6d28 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: Please watch out for upcomming announcements. ______________________________________________________________________________ 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 advise against subscribing 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 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 toplevel 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.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: xmcd Announcement-ID: SuSE-SA:2001:025 Date: Friday, Aug 3rd 2001 18:30 MEST Affected SuSE versions: (6.0, 6.1, 6.2,) 6.3, 6.4, 7.0, 7.1, 7.2 Vulnerability Type: local privilege escalation Severity (1-10): 4 SuSE default package: no Other affected systems: yes Content of this advisory: 1) security vulnerability resolved: yes problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information Cda, a setuid commandline part of xmcd, a X11/Motif audio CD player by Ti Kan <ti(a)amb.org>, was found vulnerable by a link attack and some bufferoverflows. These bugs could be exploited by an adversary, who has access to the system, to overwrite files or gain higher privileges. As a temporary fix, just remove the setuid bit from cda: /bin/chmod 755 /usr/X11R6/bin/cda or let just trusted users execute cda: /bin/chown root.trusted /usr/X11R6/bin/cda /bin/chmod 4750 /usr/X11R6/bin/cda Don't forget to add these changes to your /etc/permissions.local file Users of SuSE 7.2 with permissions.secure or permissions.paranoid activated are safe, because setuid is already removed. Thanks to Paul Starzetz <paul(a)starzetz.de>, who reportes the link attack and to Ti Kan <ti(a)amb.org>, the author of xmcd, for his fast response and help.

An announcement will be released soon. - dqs dex(a)raza-mexicana.org has found an exploitable buffer overflow bug in the dsh program from the dqs package on SuSE Linux distributions. To workaround the problem, do "chmod -s /usr/bin/dsh" and change the files /etc/permissions* to reflect the change. If you do not need the dqs package, then deinstall it (rpm -e dqs). Packages for most of the supported SuSE Linux distributions are available at the usual location ftp://ftp.suse.com/pub/suse/<arch>/<dist> for download and installation/update. Do not forget to change the files /etc/permissions* to remove the suid-bit from the dsh program. Please note that we will not issue a dedicated security announcement for this specific bug. - pcp Paul Starzetz discovered a security weakness in the setuid root program /usr/share/pcp/bin/pmpost. The common library in pcp trusts the environment that has been supplied by the user, regardless of privileged execution or not. By consequence, a user can specify the configuration file and therefore write to files owned by root. The problem is not based on insecurely following symlinks as stated by Paul Starzetz. The pcp package is not installed by default in SuSE Linux distributions. We have provided update packages for the SuSE Linux distributions version 7.1 and 7.2 that remove the setuid bit from the pmpost binary. Versions before SuSE-7.1 were not affected because the setuid bit was not set. We thank Keith Owens and Mark Goodwin from Silicon Graphics for responding quickly and for publishing a new version of the pcp package which will be included in future releases of the SuSE Linux distribution. For more information see the /usr/share/doc/packages/pcp directory of your SuSE Linux installation after installing the update package, or go to obtained from http://oss.sgi.com/projects/pcp/download . Please note that there will not be a dedicated security announcement for this specific bug. - fetchmail (fetchml) New fetchmail packages are available on the ftp server. The packages cure a buffer overflow that can be exploited by sending a victim a specially designed email, waiting for the victim's fetchmail program to pick up the email. We are preparing a security announcement for this problem. - openssh update packages for the openssh package after (and including) SuSE-6.4 are available on our ftp servers ftp.suse.de (for < 7.1) or ftp.suse.com (for >= 7.1). We are currently checking for a non-security related irregularity in sshd's behaviour under faulty setup conditions. - exim SuSE Linux distributions do not contain the exim Mail Transport Agent (See http://www.exim.org/ for details) and are therefore not susceptible to the recently found security-related bugs. - webmin SuSE Linux distributions do not contain the webmin administration web frontend (See http://www.webmin.org/ for details) and are therefore not vulnerable to the recently found security-related problems in the software. ______________________________________________________________________________ 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 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 toplevel 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.
