Kernel Backdoor (April Fool's joke)
by draht＠suse.de 29 Mar '01

29 Mar '01

-----BEGIN PGP SIGNED MESSAGE----- To those involved in Linux security: The latest release of "Linux-Magazin", a monthly German magazine that focuses on Linux, contains an article by Mirko Dölle about security problems in the Linux kernel. In particular, the article argues that IP packets could be forwarded to the address 208.47.125.33 (there is a PTR record at gary7.nsa.gov, which has an A record back to the same address). Many German Linux users have been calling SuSE support to learn details on how to deal with this problem, not willing to believe that the article is an April Fool's joke on security. None of the claims are correct, which makes a kernel update unnecessary for this particular problem. Now, as inclined readers of security mailing lists may have noticed, there are indeed security problems in the Linux kernel. These problems are no backdoors of any kind, and they are not related to the article mentioned above. In addition, the known kernel security issues are not remotely exploitable, which means that local shell access is needed to take advantage of the weaknesses. The weaknesses allow for a local attacker to gain superuser access to the system. SuSE will provide update packages for the supported distributions 6.3, 6.4, 7.0 and 7.1 shortly that eliminate the known problems. The SuSE kernels are standard kernels, equipped with a set of patches that introduce drivers and many other enhancements to the standard Linux kernel. The update packages are currently being tested and will be available and announced as soon as possible. As an information for those who compile and install their own kernels: The freshly released Linux kernel version 2.2.19 fixes the known issues in the kernel. It should run smoothly on all 6.x SuSE Linux distributions, but please note that 2.2.19 requires update packages for the lvm and/or the raidtools (formerly mdutils) package if lvm (logical volume manager) or the software raid facility of the Linux kernel are used. The lvm package is available for download from our ftp server ftp.suse.com, the raidtools package will follow soon.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: joe Announcement-ID: SuSE-SA:2001:09 Date: Tuesday, March 27th, 2001 17.03 MEST Affected SuSE versions: 6.1, 6.2, 6.3, 6.4, 7.0, 7.1 Vulnerability Type: local privilege escalation Severity (1-10): 3 SuSE default package: yes Other affected systems: all system using joe Content of this advisory: 1) security vulnerability resolved: joe 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 A bug in joe(1), a userfriendly text editor, was found by Christer Öberg of Wkit Security AB a few weeks ago. After starting joe(1) it tries to open its configuration file joerc in the current directory, the users home directory and some other locations. joe(1) doesn't check the ownership of joerc when trying the current directory. An attacker could place a malicious joerc file in a public writeable directory, like /tmp, to execute commands with the privilege of any user (including root), which runs joe while being in this directory. Download the update package from locations desribed below and install the package with the command `rpm -Uhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/ap1/joe-2.8-300.i386.rpm 3140f1eb79eb246ad98f7687de517371 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/joe-2.8-300.src.rpm 0c04bb25b8ae452f1fcdfe11af32e1b6 SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/ap1/joe-2.8-304.i386.rpm 2a406de36322fc7bc28aaeca0bbdf54d source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/joe-2.8-304.src.rpm 2aac0d130597d580d96c75d59397958c SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/ap1/joe-2.8-303.i386.rpm 348a5e4a981f76943c77431606e5c3b2 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/joe-2.8-303.src.rpm 9f938aa365460257baf56f5f92f565ee SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/ap1/joe-2.8-302.i386.rpm 236ec54a0251859e1c2c1fc4018b5dae source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/joe-2.8-302.src.rpm 49b638dd238cacc8e99048ee5a8024ea SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/ap1/joe-2.8-302.i386.rpm 094577b41a2ad5baa0d16f4d53378d0e source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/joe-2.8-302.src.rpm 78333a2bac40b08db1e54ccaf1380caf SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/ap1/joe-2.8-305.i386.rpm 72fbb78af21f3878f1ae8b8bc87c96f4 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/joe-2.8-305.src.rpm b4fbe27a24bf66d60db45da3c3d13020 Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/ap1/joe-2.8-290.sparc.rpm eeb78e413ee0b48d39ccdab29228ae80 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/joe-2.8-290.src.rpm f29199161ffd38f3f26c82b5d21ba89b SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/ap1/joe-2.8-292.sparc.rpm d1d70f58df37de53f05734d90be596fa source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/joe-2.8-292.src.rpm 45091ece9cb66e4f093d07b0386fd2b9 AXP Alpha Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/ap1/joe-2.8-296.alpha.rpm 85e609519bbfbbc0be5aec7b8de2dffc source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/joe-2.8-296.src.rpm ce623f8a73b1f6395eb9498324cc1e21 SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/ap1/joe-2.8-293.alpha.rpm d930c6a2f0757f51f04409946f6152f8 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/joe-2.8-293.src.rpm 0b20e5bd36f0feeaf78cb4815566e982 SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/ap1/joe-2.8-293.alpha.rpm 6278e4dd4a42d4e091d1a08e3f617fa2 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/joe-2.8-293.src.rpm 88f428cc9c916b9159dfb54144c7802e SuSE-6.1 ftp://ftp.suse.com/pub/suse/axp/update/6.1/ap1/joe-2.8-295.alpha.rpm 3e531066b0495be2261f02ef2d4583f0 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.1/zq1/joe-2.8-295.src.rpm 1d7796f1fad01365e40a944f0db84470 PPC PowerPC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/ap1/joe-2.8-272.ppc.rpm f11094b9f1afeb04786030e3a140ed03 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/joe-2.8-272.src.rpm 4058ea46c9d75976a24a6ac419fc19d5 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/ap1/joe-2.8-274.ppc.rpm c385a2ca601cf9b01ad2d39433d6a872 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/joe-2.8-274.src.rpm b667ea68d356a9582d3696ad68869c69 SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/ap1/joe-2.8-273.ppc.rpm 4f6c2c20e961aea4987381d12692af6c source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/joe-2.8-273.src.rpm 8c3ebda871c54afc11a24d80d207c34e ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - We are in the process of preparing update packages for the man package which has been found vulnerable to a commandline format string bug.

SuSE Security Announcement: eperl (SuSE-SA:2001:08)

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: eperl Announcement-ID: SuSE-SA:2001:08 Date: Tuesday, March 27th, 2001 16.00 MEST Affected SuSE versions: 6.3, 6.4, 7.0, 7.1 Vulnerability Type: local and remote compromise Severity (1-10): 6 SuSE default package: no Other affected systems: all system using eperl package Content of this advisory: 1) security vulnerability resolved: eperl 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 The ePerl program is a interpreter for the Embedded Perl 5 Language. It's main purpose is to serve as Webserver scripting language for dynamic HTML page programming. Besides this it could also serve as a standalone Unix filter. Fumitoshi Ukai and Denis Barbier have found several potential buffer overflows, which could lead to local privilege escalation if installed setuid (note: it's not installed setuid per default) or to remote compromise. There is currently no efficient measure against the security problems in the eperl perl interpreter other than not using or updating it. SuSE provides update packages for the defective software. SuSE Linux version before 6.3 don't include the eperl package. Download the update package from locations described below and install the package with the command `rpm -Uhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/d2/eperl-2.2.14-206.i386.rpm e613b06d47dcfb7bbcea8c3d0c0e678b source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/eperl-2.2.14-206.src.rpm c58a95f3b8ae757ea4d72f3157e2ea62 SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/d1/eperl-2.2.14-203.i386.rpm e66520cc0062e25495941542dd5b1f82 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/eperl-2.2.14-203.src.rpm 34d6682524154c9fb7b5fbec4f4ea82e SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/d1/eperl-2.2.14-203.i386.rpm 4b6a5a89899320a8eeb35c149ae111f5 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/eperl-2.2.14-203.src.rpm 062b14716e52f2649f4380a6a6e4e7f9 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/d1/eperl-2.2.14-202.i386.rpm ba75d7f4a64329a3b5c324b3f0742575 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/eperl-2.2.14-202.src.rpm c7ae001d4668ba3a0524f94429b1e4e6 Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/d2/eperl-2.2.14-193.sparc.rpm 9752f8b9df6ac1ffdc68cb4b552d6491 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/eperl-2.2.14-193.src.rpm f09a1ce9288c201ae63e193914fc84ce SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/d1/eperl-2.2.14-191.sparc.rpm 900eddc134215569fc88d11ce14c11f3 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/eperl-2.2.14-191.src.rpm 76aaa0efa8ae1c84b80201f73462fc26 AXP Alpha Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/d1/eperl-2.2.14-195.alpha.rpm d7b4be8d988f8cd501a33f9d2fb12a07 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/eperl-2.2.14-195.src.rpm b0379287f9078fcd244cc720fad92c4d SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/d1/eperl-2.2.14-195.alpha.rpm 78241206bc1b3927effdb5b1aa4d0ed5 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/eperl-2.2.14-195.src.rpm 325a04ec8c5c3da6b9c2fdf4e2c6c901 SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/d1/eperl-2.2.14-194.alpha.rpm 88a09004e5c0c2e6174785207e111318 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/eperl-2.2.14-194.src.rpm a04cfa3e64aac49f6c148992e9a50189 PPC Power PC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/d2/eperl-2.2.14-178.ppc.rpm 3e05c702aca97db476155054d113ff95 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/eperl-2.2.14-178.src.rpm 67849b0c1c053eca482508fe2eac3042 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/d1/eperl-2.2.14-177.ppc.rpm 35584e2f1bcebced98fad2ae241824da source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/eperl-2.2.14-177.src.rpm 98046dce35c4adfba57cc54c018376d7 SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/d1/eperl-2.2.14-176.ppc.rpm 9c36bad7ec2e8f6c31307729c7d21bc8 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/eperl-2.2.14-176.src.rpm eeaf1144dd659fe13b6a943bf40bf65b S/390 Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/s390/update/7.0/d1/eperl-2.2.14-182.s390.rpm 416974a30c9c9e435e028f2807e15a51 source rpm: ftp://ftp.suse.com/pub/suse/s390/update/7.0/zq1/eperl-2.2.14-182.src.rpm b14c7d9cbb969cda54b0d9f599f1b5cc ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - We are in the process of preparing update packages for the man package which has been found vulnerable to a commandline format string bug.

However, we prefer to provide a fixed update package to make sure that the daemon is on the safe side. in.ftpd(8) will be invoked by inetd(8) and is activated by default. timed(8): The time server daemon timed(8), which is started at boot time, tries to synchronize the local host time with the time of other machines on the local area network. A bug in timed(8) was reported by the FreeBSD Security Officer, that could be triggered remotely to crash the time server daemon. For SuSE 6.1-6.4 in.ftpd and timed were part of nkitb. Users of SuSE 7.0 need to download the nkitserv package for both in.ftpd and timed. The bug in in.ftpd is fixed in SuSE 7.1, so nkitserv for SuSE 7.1 just includes a new version of timed(8). Download the update package from locations desribed below and install the package with the command `rpm -Uhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n1/nkitserv-2001.3.16-0.i386.rpm c4313f92a36916f0eba0b8837c9c0c81 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/nkitb-2001.3.16-1.src.rpm ec452523fa25c8aed962fbd3349d1f3d SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/n1/nkitserv-2001.3.16-0.i386.rpm 02772824805c6c4293bd1750d7bda6d3 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/nkitb-2001.3.16-1.src.rpm 5d301edc1b1ec9111572815aace33984 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/a1/nkitb-2001.3.16-1.i386.rpm 842dea179cc449c4af25accf0c3f38ec source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/nkitb-2001.3.16-1.src.rpm c099e7c1194b7706100453a89433b59c SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/a1/nkitb-2001.3.16-0.i386.rpm 768a636df4731cd8efd181aa2eaf2e60 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/nkitb-2001.3.16-0.src.rpm b705425c4c3cb70ebf9cd1345c92104a SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/a1/nkitb-2001.3.16-0.i386.rpm cbae31148c79c91a1443f79ee1ba34d3 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/nkitb-2001.3.16-0.src.rpm d287c01d35d00756ecbf8da04556037c SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/a1/nkitb-2001.3.16-0.i386.rpm 5f45ade69a9e8c2756e671c4a6e3522a source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/nkitb-2001.3.16-0.src.rpm 62b969c4e666f3ea71b6ce6b31762718 Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/n1/nkitserv-2001.3.16-0.sparc.… 142329dcae76a1603c0d84836192e357 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/nkitb-2001.3.16-0.src.rpm 5bd9123cecba6ddd42cc965c599f383e SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/n1/nkitserv-2001.3.16-0.sparc.… 07ed33c76c7ae2df5b877003b254944d source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/nkitb-2001.3.16-0.src.rpm 66ba7b71624f636e24e2d628c8f06e81 AXP Alpha Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/n1/nkitserv-2001.3.16-0.alpha.rpm 5fcf177588788eb069bdb69332046d23 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/nkitb-2001.3.16-0.src.rpm c27ed3bf0c293eaa77fe5a8fa960e95d SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/a1/nkitb-2001.3.16-0.alpha.rpm 385fa60c0c216f1d9e61afd52d37df93 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/nkitb-2001.3.16-0.src.rpm 5ba60084740c9be9f89a729e2d21a77c SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/a1/nkitb-2001.3.16-0.alpha.rpm 8a9e207a77e3c7f954e8faa91954f7aa source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/nkitb-2001.3.16-0.src.rpm 53f8a03feacc7fb81b92a726c8e81d21 SuSE-6.1 ftp://ftp.suse.com/pub/suse/axp/update/6.1/a1/nkitb-2001.3.16-0.alpha.rpm 359a3432f73220cecd42ba0b365d5e06 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.1/zq1/nkitb-2001.3.16-0.src.rpm e0ccf6395312f9c33518f5f083c9d51f PPC PowerPC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/n1/nkitserv-2001.3.16-0.ppc.rpm 37bf5a963bc93215084b5634e864479c source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/nkitb-2001.3.16-0.src.rpm c31af637f58d9b43db542657b02bc772 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/n1/nkitserv-2001.3.16-1.ppc.rpm ddc1dcfb94ba90f3cbdf395f89dd3b84 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/nkitb-2001.3.16-1.src.rpm 2fa9c58b871248172285a64107e3be7c SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/a1/nkitb-2001.3.16-0.ppc.rpm 1dc4c831b5f6bd344ab8f511497b3fa5 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/nkitb-2001.3.16-0.src.rpm 5529e5f63e2391ab1669efa0a8c33b57 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - joe (configuration file vulnerability): The problem has been reported on multiple security-related mailing lists.

As a reaction to these bugs, the spaceboom game has been dropped from the distribution. We recommend to deinstall the game from our 6.x and 7.x distribution by using the command `rpm -e spaceŽ, or to remove the suid bit from the file /usr/games/SpaceBoom/SpaceBoom using the command `chmod -s /usr/games/SpaceBoom/SpaceBoomŽ. (Note: removing the suid bit prevents the game from being used by non-root users and from being reinstalled after removal.) - We are in the process of preparing update packages for the man package which has been found vulnerable to a commandline format string bug. The man command is installed suid man on SuSE systems. When exploited, the bug can be used to install a different man binary to introduce a trojan into the system. As an interim workaround, we recommend to `chmod -s /usr/bin/manŽ and ignore the warnings and errors when viewing manpages. - The file browser MidnightCommander (mc) is vulnerable to unwanted program execution. Updates are currently being built. - New RPMs, that fix' a vulnerbility in the eperl package for SuSE 6.1-7.1 are currently being built. ______________________________________________________________________________ 3) standard appendix: 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: cups
by krahmer＠suse.de 05 Mar '01

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: cups Announcement-ID: SuSE-SA:2001:05 Date: Monday, March 5th, 2001 13:10:13 MET Affected SuSE versions: 7.1 Vulnerability Type: local/remote root compromise Severity (1-10): 5 SuSE default package: no Other affected systems: All UN*X-systems using cups < 1.1.6. Content of this advisory: 1) security vulnerability resolved: cups 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 CUPS is an implementation of the Internet Printing Protocol (IPP) and is used as an alternative to the lpr and LPRng packages. The CUPS package aims to be a comprehensive printing solution for UN*X-systems. In SuSE-7.1 distribution, the cups package is not used by any configuration utilities unless the admin has decided to configure the package manually. The cups package has been introduced in the SuSE-7.1 distribution; enhanced support for future releases of the SuSE Linux distribution is planned. A SuSE-internal security audit conducted by Sebastian Krahmer and Thomas Biege revealed several overflows as well as insecure file handling. These bugs have been fixed by adding length-checks and securing the file-access. For a temporary workaround, remove the suid-bit from the 'lppasswd' program. Make sure nobody from outside your network can access the CUPS-server running on port 631. Allowing access to this port from outside is a bad idea regardless whether or not the used version is vulnerable. No remote-exploits are known yet. Download the update package from locations desribed below and install the package with the command `rpm -Uhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/d3/cups-devel-1.1.6-13.i386.rpm 23c6484952ab0c1de81e2db38bcd3afc SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n2/cups-1.1.6-13.i386.rpm 812e0c47dcfe508eb9e8ccb38165b6d7 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/cups-1.1.6-13.src.rpm 204cea2ad6a61293c191e70a2cacdc82 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: Effective Monday, March 19 2001, five weeks after the release of the new SuSE-7.1 distribution, SuSE will discontinue support for the SuSE-linux distributions SuSE-6.0 SuSE-6.1 and SuSE-6.2. SuSE puts much effort into adding security improvements (patches) to the software instead of publishing a new version; the same program with a fix for a specific problem promises to work just as reliable as the original version from the distribution, whereas new versions introduce new functionality which changes the behaviour. In some cases however, especially if the security leak is based on problematic design decisions or when the fix(es) are fairly large, the only reasonable fix for a security problem is to update to a newer version of the software. These newer versions tend to become incompatible with our older distribution releases because of missing features in the operating system environment. This forces us to focus on the distributions of a newer release date. The remaining distributions SuSE-6.3, SuSE-6.4, SuSE-7.0 and SuSE-7.1 for the Intel i386, AXP Alpha, SPARC as well as PPC Power PC platforms will continue to be supported for a two-year period after the release of the respective distribution. ______________________________________________________________________________ 3) standard appendix: SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion.
