Hi, I resend advisory SuSE-SA:2001:06, because of a wrong signature. -----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: pop Announcement-ID: SuSE-SA:2001:06 Date: Wednesday, March 21th, 2001 19.19 MEST Affected SuSE versions: 6.1 Vulnerability Type: remote command execution Severity (1-10): 2 SuSE default package: no Other affected systems: all system using the pop package Content of this advisory: 1) security vulnerability resolved: imapd, ipop2d, ipop3d 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 eMail access daemons imapd(8), ipop2d(8) and ipop3d(8) of SuSE 6.1 are vulnerable to several buffer overflows. Due to a misconfiguration these vulnerbilities could be triggered remotely after a user had been authenticated. 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-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/n1/pop-2001.3.21-0.i386.rpm 1277deee87f3d1553ee18ae078d646aa source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/pop-2001.3.21-0.src.rpm ce326335b36e51b6a635b69fc0106911 AXP Alpha Platform: SuSE-6.1 ftp://ftp.suse.com/pub/suse/axp/update/6.1/n1/pop-2001.3.21-0.alpha.rpm 33405d29e279795d99853a1235a821f9 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.1/zq1/pop-2001.3.21-0.src.rpm eecd7c9ac81397f9eb7b2bee01a0154d ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - joe (configuration file vulnerability): The problem has been reported on multiple security-related mailing lists. We are about to provide fixed packages. - The game spaceboom (SVGA shoot'em up) has been found vulnerable to multiple vulnerabilities. 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. - A new nkitb/nkitserv package will be availabe soon. This update adresses bugs in timed, in.ftpd. - 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.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: nkitb/nkitserv Announcement-ID: SuSE-SA:2001:07 Date: Thursday, March 22th, 2001 19.06 MEST Affected SuSE versions: 6.1, 6.2, 6.3, 6.4, 7.0, 7.1 Vulnerability Type: remote denial-of-service Severity (1-10): 4 SuSE default package: yes: in.ftpd, no: timed Other affected systems: all system using in.ftpd (OpenBSD port) or timed Content of this advisory: 1) security vulnerability resolved: timed, in.ftpd 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 Two parts of the nkitb/nkitserv package are vulnerable to security related bugs. in.ftpd(8): A one-byte bufferoverflow was discovered in the OpenBSD port of the FTP daemon in.ftpd(8) several weeks ago. This bug could just be triggered by authenticated users, which have write access. This bug is believed to not be exploitable under Linux. 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.

SuSE Security Announcement: cups

-----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.

SuSE Security Announcement: ssh (SuSE-SA:2001:04)
by draht＠suse.de 16 Feb '01

16 Feb '01

The announcement is being resent because of a small error in the "Affected SuSE versions" section: SuSE-7.1 is vulnerable, too. -----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: ssh Announcement-ID: SuSE-SA:2001:04 Date: Friday, February 16th, 2000 18:00 MET Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0, 7.1 Vulnerability Type: possible remote root compromise Severity (1-10): 9 SuSE default package: yes, no (openssh is default after SuSE-6.3) Other affected systems: Unix systems with sshd running Content of this advisory: 1) security vulnerability resolved: ssh 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 SuSE distributions contain the ssh package in the version 1.2.27. No later version is provided because of licensing issues. SuSE maintains the 1.2.27 version in a patched package. Three new patches have been added that workaround three independent security problems in the ssh package: a) SSHD-1 Logging Vulnerability (discovered and published by Jose Nazario, Crimelabs). Attackers can remotely brute-force passwords without getting noticed or logged. In the ssh package from the SuSE distribution, root login is allowed, as well as password authentication. Even though brute-forcing a password may take an enormous amount of time and resources, the issue is to be taken seriously. b) SSH1 session key recovery vulnerability (by (Ariel Waissbein, Agustin Azubel) - CORE SDI, Argentina, and David Bleichenbacher). Captured encrypted ssh traffic can be decrypted with some effort by obtaining the session key for the ssh session. The added patch in our package causes the ssh daemon to generate a new server key pair upon failure of an RSA operation (please note that the patch supplied with Iván Arce on bugtraq on Wed, 7 Feb 2001 has been corrected later on!). c) In 1998, the ssh-1 protocol was found to be vulnerable to an attack where arbitrary sequences could be inserted into the ssh-1 protocol layer. The attack was called "crc32 compensation attack", and a fix was introduced (crc compensation attack detector in the ssh -v output) into the later versions of ssh. Michal Zalewski discovered that the fix in its most widely used implementation is defective. An integer overflow allows an attacker to overwrite arbitrary memory in the sshd process' address space, which potentionally results in a remote root compromise. There are easy resorts that can be offered: a) switch to openssh (please use the openssh packages on ftp.suse.com from the same update directories as the ssh package update URLs below indicate). openssh is a different implementation of the ssh protocol that is compatible to the protocol versions 1 and 2. Openssh Version 2.3.0 does not suffer from the problems listed above. Versions before 2.3.0 are vulnerable to other problems, so please use the updates from the update directory on the ftp.suse.de ftp server. See section 2) of this announcement for the md5sums of the packages. b) upgrade your ssh package from the locations described below. 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. SPECIAL INSTALL INSTRUCTIONS: ============================== If you run a sshd (secure shell daemon) server on your system, then the daemon process must be restarted for the update package to become active after installation of the update rpm. You can do this easily with the command (ran as root): kill -15 `cat /var/run/sshd.pid` After this, you can start the daemon using the command rcsshd start It should be possible now to log on again to your server as usual. Please consult the syslogs in /var/log if this is not the case. Warning: killing all instances of sshd on a system might render the system inaccessible from remote, especially if secure shell is your only method to access the system. Be careful to not lock yourself out. Note: The packages on our German ftp server have been built again to correct one of the patches. The package for the 6.1-i386 distribution has finished building a few minutes ago and uses the same name as the build from Wednesday. Use the --force commandline option for the rpm command if you have used the package that was published before the release date of this announcement. i386 Intel Platform: SuSE-7.1 ftp://ftp.suse.de/pub/suse/i386/update/7.1/sec2/ssh-1.2.27-226.i386.rpm ae68bf3ac28b5e81f9c5f2a1d1d8980e source rpm: ftp://ftp.suse.de/pub/suse/i386/update/7.1/zq1/ssh-1.2.27-226.src.rpm d332e662daff71ff7d10cf4d962b6933 SuSE-7.0 ftp://ftp.suse.de/pub/suse/i386/update/7.0/sec1/ssh-1.2.27-220.i386.rpm f88b339dea96ef186e70872ce9444c24 source rpm: ftp://ftp.suse.de/pub/suse/i386/update/7.0/zq1/ssh-1.2.27-220.src.rpm 93ca5fc96c103a5f9adee16cb319195c SuSE-6.4 ftp://ftp.suse.de/pub/suse/i386/update/6.4/sec1/ssh-1.2.27-86.i386.rpm 3f1b41116b7c7d63c791de4fdca9d1ee source rpm: ftp://ftp.suse.de/pub/suse/i386/update/6.4/zq1/ssh-1.2.27-86.src.rpm 3a8d859f2ae9751852339c642b07b4cf SuSE-6.3 ftp://ftp.suse.de/pub/suse/i386/update/6.3/sec1/ssh-1.2.27-86.i386.rpm 3f1b41116b7c7d63c791de4fdca9d1ee source rpm: ftp://ftp.suse.de/pub/suse/i386/update/6.3/zq1/ssh-1.2.27-86.src.rpm 3a8d859f2ae9751852339c642b07b4cf SuSE-6.2 ftp://ftp.suse.de/pub/suse/i386/update/6.2/sec1/ssh-1.2.27-210.i386.rpm b29822198dc6430167465706965e3499 source rpm: ftp://ftp.suse.de/pub/suse/i386/update/6.2/zq1/ssh-1.2.27-210.src.rpm 4a2130635f702bb266748b9e4838877a SuSE-6.1 ftp://ftp.suse.de/pub/suse/i386/update/6.1/sec1/ssh-1.2.27-210.i386.rpm 17f281262edd689d9861c099489cbcc6 source rpm: ftp://ftp.suse.de/pub/suse/i386/update/6.1/zq1/ssh-1.2.27-210.src.rpm 5e12e0086f61bba2f37c4ccbc4282a92 Sparc Platform: SuSE-7.0 ftp://ftp.suse.de/pub/suse/sparc/update/7.0/sec1/ssh-1.2.27-221.sparc.rpm e1545287f954d089707c55a66598c318 source rpm: ftp://ftp.suse.de/pub/suse/sparc/update/7.0/zq1/ssh-1.2.27-221.src.rpm f37a8b3addaf70711d91f6a3f788a8b3 AXP Alpha Platform: SuSE-7.0 ftp://ftp.suse.de/pub/suse/axp/update/7.0/sec1/ssh-1.2.27-221.alpha.rpm 77bd0dcda5df929fba07d56de2bf3399 source rpm: ftp://ftp.suse.de/pub/suse/axp/update/7.0/zq1/ssh-1.2.27-221.src.rpm 77305ae844c9b68e8af559ccf81417e8 SuSE-6.4 ftp://ftp.suse.de/pub/suse/axp/update/6.4/sec1/ssh-1.2.27-86.alpha.rpm 7a8d7086c8b99822b020f3c9d0e4764e source rpm: ftp://ftp.suse.de/pub/suse/axp/update/6.4/zq1/ssh-1.2.27-86.src.rpm e75660e54edc2cf38086b4de3da91881 SuSE-6.3 ftp://ftp.suse.de/pub/suse/axp/update/6.3/sec1/ssh-1.2.27-212.alpha.rpm 671761326c11c9eac50c3d992b550bdf source rpm: ftp://ftp.suse.de/pub/suse/axp/update/6.3/zq1/ssh-1.2.27-212.src.rpm 5472b658aac01bea8667769a04e0e92d PPC Power PC Platform: SuSE-7.0 ftp://ftp.suse.de/pub/suse/ppc/update/7.0/sec1/ssh-1.2.27-220.ppc.rpm ec7274c8a88b6ce5420c91da0622f94c source rpm: ftp://ftp.suse.de/pub/suse/ppc/update/7.0/zq1/ssh-1.2.27-220.src.rpm 1ae9f7cf4c7099f5cad8cb0ccc8f3e5d SuSE-6.4 ftp://ftp.suse.de/pub/suse/ppc/update/6.4/sec1/ssh-1.2.27-86.ppc.rpm fc3cb2e3b927c7ffc5e8374e183f860e source rpm: ftp://ftp.suse.de/pub/suse/ppc/update/6.4/zq1/ssh-1.2.27-86.src.rpm 439abdfb6f56e2c0d3880cddd103935f ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: -

Linux kernel upgrade. Several security flaws have been found in the linux-2.2.x kernel versions. The only suitable workaround is to upgrade to a newer kernel version. SuSE provides kernels that have been expanded with several dozen device drivers that are not included in the standard main stream kernel. While working on the kernel update packages for our distributions, more security problems were discovered. Currently, several persons audit code in the kernel, so that more problems are expected to be discovered in the very near future. Since kernel updates are very time-consuming on behalf of the system administrator, we decided to not publish a new kernel package each week. Instead, the new kernel packages with all known security bugs fixed will be published by the midth/end of next week. In the meanwhile, administrators who require immediate updates, please go to ftp.kernel.org (or one of its mirrors, respectively) and get Alan Cox' prepatches for the 2.2.19 version of the Linux kernel. The directory usually is /pub/linux/kernel/people/alan/2.2.19pre, his latest patch is pre-patch-2.2.19-13.gz. This patch fixes all currently publically known security problems in the Linux v2.2 kernel. For those who are not experienced in patching and installing kernels, we recommend to wait for the release of the SuSE Linux kernel update packages. - From SuSE-SA:2001:03 (bind8): The sparc update packages were pending because of build bottlenecks.

SuSE Security Announcement: ssh (SuSE-SA:2001:04)
by draht＠suse.de 16 Feb '01

16 Feb '01

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: ssh Announcement-ID: SuSE-SA:2001:04 Date: Friday, February 16th, 2000 18:00 MET Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0 Vulnerability Type: possible remote root compromise Severity (1-10): 9 SuSE default package: yes, no (openssh is default after SuSE-6.3) Other affected systems: Unix systems with sshd running Content of this advisory: 1) security vulnerability resolved: ssh 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 SuSE distributions contain the ssh package in the version 1.2.27. No later version is provided because of licensing issues. SuSE maintains the 1.2.27 version in a patched package. Three new patches have been added that workaround three independent security problems in the ssh package: a) SSHD-1 Logging Vulnerability (discovered and published by Jose Nazario, Crimelabs). Attackers can remotely brute-force passwords without getting noticed or logged. In the ssh package from the SuSE distribution, root login is allowed, as well as password authentication. Even though brute-forcing a password may take an enormous amount of time and resources, the issue is to be taken seriously. b) SSH1 session key recovery vulnerability (by (Ariel Waissbein, Agustin Azubel) - CORE SDI, Argentina, and David Bleichenbacher). Captured encrypted ssh traffic can be decrypted with some effort by obtaining the session key for the ssh session. The added patch in our package causes the ssh daemon to generate a new server key pair upon failure of an RSA operation (please note that the patch supplied with Iván Arce on bugtraq on Wed, 7 Feb 2001 has been corrected later on!). c) In 1998, the ssh-1 protocol was found to be vulnerable to an attack where arbitrary sequences could be inserted into the ssh-1 protocol layer. The attack was called "crc32 compensation attack", and a fix was introduced (crc compensation attack detector in the ssh -v output) into the later versions of ssh. Michal Zalewski discovered that the fix in its most widely used implementation is defective. An integer overflow allows an attacker to overwrite arbitrary memory in the sshd process' address space, which potentionally results in a remote root compromise. There are easy resorts that can be offered: a) switch to openssh (please use the openssh packages on ftp.suse.com from the same update directories as the ssh package update URLs below indicate). openssh is a different implementation of the ssh protocol that is compatible to the protocol versions 1 and 2. Openssh Version 2.3.0 does not suffer from the problems listed above. Versions before 2.3.0 are vulnerable to other problems, so please use the updates from the update directory on the ftp.suse.de ftp server. See section 2) of this announcement for the md5sums of the packages. b) upgrade your ssh package from the locations described below. 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. SPECIAL INSTALL INSTRUCTIONS: ============================== If you run a sshd (secure shell daemon) server on your system, then the daemon process must be restarted for the update package to become active after installation of the update rpm. You can do this easily with the command (ran as root): kill -15 `cat /var/run/sshd.pid` After this, you can start the daemon using the command rcsshd start It should be possible now to log on again to your server as usual. Please consult the syslogs in /var/log if this is not the case. Warning: killing all instances of sshd on a system might render the system inaccessible from remote, especially if secure shell is your only method to access the system. Be careful to not lock yourself out. Note: The packages on our German ftp server have been built again to correct one of the patches. The package for the 6.1-i386 distribution has finished building a few minutes ago and uses the same name as the build from Wednesday. Use the --force commandline option for the rpm command if you have used the package that was published before the release date of this announcement. i386 Intel Platform: SuSE-7.1 ftp://ftp.suse.de/pub/suse/i386/update/7.1/sec2/ssh-1.2.27-226.i386.rpm ae68bf3ac28b5e81f9c5f2a1d1d8980e source rpm: ftp://ftp.suse.de/pub/suse/i386/update/7.1/zq1/ssh-1.2.27-226.src.rpm d332e662daff71ff7d10cf4d962b6933 SuSE-7.0 ftp://ftp.suse.de/pub/suse/i386/update/7.0/sec1/ssh-1.2.27-220.i386.rpm f88b339dea96ef186e70872ce9444c24 source rpm: ftp://ftp.suse.de/pub/suse/i386/update/7.0/zq1/ssh-1.2.27-220.src.rpm 93ca5fc96c103a5f9adee16cb319195c SuSE-6.4 ftp://ftp.suse.de/pub/suse/i386/update/6.4/sec1/ssh-1.2.27-86.i386.rpm 3f1b41116b7c7d63c791de4fdca9d1ee source rpm: ftp://ftp.suse.de/pub/suse/i386/update/6.4/zq1/ssh-1.2.27-86.src.rpm 3a8d859f2ae9751852339c642b07b4cf SuSE-6.3 ftp://ftp.suse.de/pub/suse/i386/update/6.3/sec1/ssh-1.2.27-86.i386.rpm 3f1b41116b7c7d63c791de4fdca9d1ee source rpm: ftp://ftp.suse.de/pub/suse/i386/update/6.3/zq1/ssh-1.2.27-86.src.rpm 3a8d859f2ae9751852339c642b07b4cf SuSE-6.2 ftp://ftp.suse.de/pub/suse/i386/update/6.2/sec1/ssh-1.2.27-210.i386.rpm b29822198dc6430167465706965e3499 source rpm: ftp://ftp.suse.de/pub/suse/i386/update/6.2/zq1/ssh-1.2.27-210.src.rpm 4a2130635f702bb266748b9e4838877a SuSE-6.1 ftp://ftp.suse.de/pub/suse/i386/update/6.1/sec1/ssh-1.2.27-210.i386.rpm 17f281262edd689d9861c099489cbcc6 source rpm: ftp://ftp.suse.de/pub/suse/i386/update/6.1/zq1/ssh-1.2.27-210.src.rpm 5e12e0086f61bba2f37c4ccbc4282a92 Sparc Platform: SuSE-7.0 ftp://ftp.suse.de/pub/suse/sparc/update/7.0/sec1/ssh-1.2.27-221.sparc.rpm e1545287f954d089707c55a66598c318 source rpm: ftp://ftp.suse.de/pub/suse/sparc/update/7.0/zq1/ssh-1.2.27-221.src.rpm f37a8b3addaf70711d91f6a3f788a8b3 AXP Alpha Platform: SuSE-7.0 ftp://ftp.suse.de/pub/suse/axp/update/7.0/sec1/ssh-1.2.27-221.alpha.rpm 77bd0dcda5df929fba07d56de2bf3399 source rpm: ftp://ftp.suse.de/pub/suse/axp/update/7.0/zq1/ssh-1.2.27-221.src.rpm 77305ae844c9b68e8af559ccf81417e8 SuSE-6.4 ftp://ftp.suse.de/pub/suse/axp/update/6.4/sec1/ssh-1.2.27-86.alpha.rpm 7a8d7086c8b99822b020f3c9d0e4764e source rpm: ftp://ftp.suse.de/pub/suse/axp/update/6.4/zq1/ssh-1.2.27-86.src.rpm e75660e54edc2cf38086b4de3da91881 SuSE-6.3 ftp://ftp.suse.de/pub/suse/axp/update/6.3/sec1/ssh-1.2.27-212.alpha.rpm 671761326c11c9eac50c3d992b550bdf source rpm: ftp://ftp.suse.de/pub/suse/axp/update/6.3/zq1/ssh-1.2.27-212.src.rpm 5472b658aac01bea8667769a04e0e92d PPC Power PC Platform: SuSE-7.0 ftp://ftp.suse.de/pub/suse/ppc/update/7.0/sec1/ssh-1.2.27-220.ppc.rpm ec7274c8a88b6ce5420c91da0622f94c source rpm: ftp://ftp.suse.de/pub/suse/ppc/update/7.0/zq1/ssh-1.2.27-220.src.rpm 1ae9f7cf4c7099f5cad8cb0ccc8f3e5d SuSE-6.4 ftp://ftp.suse.de/pub/suse/ppc/update/6.4/sec1/ssh-1.2.27-86.ppc.rpm fc3cb2e3b927c7ffc5e8374e183f860e source rpm: ftp://ftp.suse.de/pub/suse/ppc/update/6.4/zq1/ssh-1.2.27-86.src.rpm 439abdfb6f56e2c0d3880cddd103935f ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: -

Linux kernel upgrade. Several security flaws have been found in the linux-2.2.x kernel versions. The only suitable workaround is to upgrade to a newer kernel version. SuSE provides kernels that have been expanded with several dozen device drivers that are not included in the standard main stream kernel. While working on the kernel update packages for our distributions, more security problems were discovered. Currently, several persons audit code in the kernel, so that more problems are expected to be discovered in the very near future. Since kernel updates are very time-consuming on behalf of the system administrator, we decided to not publish a new kernel package each week. Instead, the new kernel packages with all known security bugs fixed will be published by the midth/end of next week. In the meanwhile, administrators who require immediate updates, please go to ftp.kernel.org (or one of its mirrors, respectively) and get Alan Cox' prepatches for the 2.2.19 version of the Linux kernel. The directory usually is /pub/linux/kernel/people/alan/2.2.19pre, his latest patch is pre-patch-2.2.19-13.gz. This patch fixes all currently publically known security problems in the Linux v2.2 kernel. For those who are not experienced in patching and installing kernels, we recommend to wait for the release of the SuSE Linux kernel update packages. - From SuSE-SA:2001:03 (bind8): The sparc update packages were pending because of build bottlenecks.

In addition to this bug, another problem allows for a remote attacker to collect information about the running bind process (this has been found by Claudio Musmarra <a9605121(a)unet.univie.ac.at>). For more information on these bugs, please visit the CERT webpage at http://www.cert.org/advisories/CA-2001-02.html and the bind bugs webpage at http://www.isc.org/products/BIND/bind-security.html . The problem is existent in the upcoming SuSE distribution 7.1 that will be available by February 10th in the CD/DVD version. There exists no reasonable method to circumvent the problems other than to update the package as described below. Please choose the update package for your distribution from the URLs listed below and download the necessary rpm files. Then, install the package using the command `rpm -Uhv file.rpmŽ. rpm packages have an internal md5 checksum that protects against file corruption. You can verify this checksum using the command (independently from the md5 signatures below) `rpm --checksig --nogpg file.rpm', The md5 sums under each package are to prove the package authenticity, independently from the md5 checksums in the rpm package format. SPECIAL INSTALL INSTRUCTIONS: ============================== If you run a bind8 nameserver on your system, please update the package immediately. In order for the updated package to become active, the nameserver process "named" needs to be restarted. Do this using the command `rcnamed restartŽ as root after performing the rpm command as shown above. Afterwards, check for the running daemon using the ps command as `ps auxŽ. The named process should show a new starting time. Repeat the `rcnamed restartŽ command if the nameserver shut down too slowly to release the socket for the new server. i386 Intel Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n2/bind8-8.2.3-92.i386.rpm e9b354dbd96f6216b9da01f2b3a0a166 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/bind8-8.2.3-92.src.rpm f77200a6c476b58980f68b5db3fd7c4b SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/n1/bind8-8.2.3-61.i386.rpm 4fdee7483fce85f2a31a1a53d2b01b76 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/bind8-8.2.3-61.src.rpm e53896d1ddfb405774a492469621af02 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/n1/bind8-8.2.3-0.i386.rpm bb25cb6ba2e54bf929f61c14b3663b3e source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/bind8-8.2.3-0.src.rpm 1033f0df4b747f1d2758fdae69a5fa17 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/n1/bind8-8.2.3-0.i386.rpm 73fe798d4afb87beecb2546ecf076f64 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/bind8-8.2.3-0.src.rpm dfe4e452d8d0a0a8ff0994e514353b3f SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/n1/bind8-8.2.3-0.i386.rpm 48b45d14724e852810de130864ab8281 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/bind8-8.2.3-0.src.rpm 22ca23ed06739effc887370bfef2d83e SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/n1/bind8-8.2.3-0.i386.rpm fc9cd0970c15246599f90ce1f5955f29 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/bind8-8.2.3-0.src.rpm 6cdf2e5c3a9a25ca98f8916de677cb70 SuSE-6.0 Please use the SuSE-6.1 packages for the SuSE-6.0 distribution on the i386 Intel Platform.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: kdesu Announcement-ID: SuSE-SA:2001:02 Date: Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0 Vulnerability Type: local root compromise Severity (1-10): 3 SuSE default package: yes Other affected systems: All KDE 1 & KDE 2 systems Content of this advisory: 1) security vulnerability resolved: kdesu 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 kdesu is a KDE frontend for su(1). When invoked it prompts for the root password and runs su(1). kdesu itself does not run setuid/setgid. However when enabling the 'keep password' option it tries to send the password across process boundaries to kdesud via a UNIX socket. During this it does not verify the identity of the listener on the other end. This allows attackers to obtain the root password. This bug has been fixed in the update packages by checking the ownership of the socket on the listener side. 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-6.1: ftp://ftp.suse.com/pub/suse/i386/update/6.1/kpa1/kdesu-0.98-187.i386.rpm 3d51f84f2dc87916bc937f3afe507c1a SuSE-6.1: ftp://ftp.suse.com/pub/suse/i386/update/6.1/kpa1/kdesu.rpm 3d51f84f2dc87916bc937f3afe507c1a source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/kdesu-0.98-187.src.rpm f8764afd475fa7a41c18603d15ce48ab SuSE-6.2: ftp://ftp.suse.com/pub/suse/i386/update/6.2/kpa1/kdesu-0.98-187.i386.rpm 027617e19c957b1ed5f42f140b62521b SuSE-6.2: ftp://ftp.suse.com/pub/suse/i386/update/6.2/kpa1/kdesu.rpm 027617e19c957b1ed5f42f140b62521b source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/kdesu-0.98-187.src.rpm 9cf3d4b0c00db4598968dd5c7e07eef7 SuSE-6.3: ftp://ftp.suse.com/pub/suse/i386/update/6.3/kpa1/kdesu-0.98-187.i386.rpm d2b6c6f3330a20c2eb7d5500de2f9df6 SuSE-6.3: ftp://ftp.suse.com/pub/suse/i386/update/6.3/kpa1/kdesu.rpm d2b6c6f3330a20c2eb7d5500de2f9df6 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/kdesu-0.98-187.src.rpm a50cc8ba1a793f9151559454fdad0a14 SuSE-6.4: ftp://ftp.suse.com/pub/suse/i386/update/6.4/kpa1/kdesu-0.98-187.i386.rpm 8f06dd49bdc00dca25eff33a3754ddee SuSE-6.4: ftp://ftp.suse.com/pub/suse/i386/update/6.4/kpa1/kdesu.rpm 8f06dd49bdc00dca25eff33a3754ddee source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/kdesu-0.98-187.src.rpm 0ca2d30cf51d1307f88581d4e240bbf0 SuSE-7.0: ftp://ftp.suse.com/pub/suse/i386/update/7.0/kpa1/kdesu-0.98-187.i386.rpm c7238ea5775939239b3857b550ca9f1b SuSE-7.0: ftp://ftp.suse.com/pub/suse/i386/update/7.0/kpa1/kdesu.rpm c7238ea5775939239b3857b550ca9f1b source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/kdesu-0.98-187.src.rpm bc74c75ba0b514f7df4f0250ccc7454a Sparc Platform: AXP Alpha Platform: SuSE-6.1: ftp://ftp.suse.com/pub/suse/axp/update/6.1/kpa1/kdesu-0.98-187.alpha.rpm 8017cd7fed463cae4bef3fa471e7e1d8 SuSE-6.1: ftp://ftp.suse.com/pub/suse/axp/update/6.1/kpa1/kdesu.rpm 8017cd7fed463cae4bef3fa471e7e1d8 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.1/zq1/kdesu-0.98-187.src.rpm 78846e4ae3f50e9264e8840da1a628a8 SuSE-6.3: ftp://ftp.suse.com/pub/suse/axp/update/6.3/kpa1/kdesu-0.98-187.alpha.rpm cf1629ba236c0c84e0f2b33101b5f1aa SuSE-6.3: ftp://ftp.suse.com/pub/suse/axp/update/6.3/kpa1/kdesu.rpm cf1629ba236c0c84e0f2b33101b5f1aa source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/kdesu-0.98-187.src.rpm da851ebaee36cb91cb1e1fca0c8bfda2 SuSE-6.4: ftp://ftp.suse.com/pub/suse/axp/update/6.4/kpa1/kdesu-0.98-187.alpha.rpm d1904cc9db320ea2c576b73633ee6bd5 SuSE-6.4: ftp://ftp.suse.com/pub/suse/axp/update/6.4/kpa1/kdesu.rpm d1904cc9db320ea2c576b73633ee6bd5 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/kdesu-0.98-187.src.rpm 27261cf8ff0ea66a597520260b832f7d SuSE-7.0: ftp://ftp.suse.com/pub/suse/axp/update/7.0/kpa1/kdesu-0.98-187.alpha.rpm be3b258eeeb3c56351b93ec8a32826db SuSE-7.0: ftp://ftp.suse.com/pub/suse/axp/update/7.0/kpa1/kdesu.rpm be3b258eeeb3c56351b93ec8a32826db source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/kdesu-0.98-187.src.rpm b7e3139377784c5cbbc4f14a5061d124 PPC Power PC Platform: SuSE-6.4: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/kpa1/kdesu-0.98-187.ppc.rpm 705afa4defc64c48f89dd94b2d52c296 SuSE-6.4: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/kpa1/kdesu.rpm 705afa4defc64c48f89dd94b2d52c296 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/kdesu-0.98-187.src.rpm 32e626fa7e8206d6803957c77062185b SuSE-7.0: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/kpa1/kdesu-0.98-187.ppc.rpm e9b4a8a26844af0bc8cb37c8d2d26530 SuSE-7.0: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/kpa1/kdesu.rpm e9b4a8a26844af0bc8cb37c8d2d26530 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/kdesu-0.98-187.src.rpm aaa092ffafe149ef8ba3acf570966e09 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - Kmail remote code execution.

SuSE Security Announcement: shlibs/glibc (SuSE-SA:2001:01)
by draht＠suse.de 26 Jan '01

26 Jan '01

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: glibc (shlibs) Announcement-ID: SuSE-SA:2001:01 Date: Friday, January 26th, 2001 15:40 MET Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0 Vulnerability Type: local root compromise Severity (1-10): 6 SuSE default package: yes Other affected systems: most Linux/glibc based systems Content of this advisory: 1) security vulnerability resolved: glibc 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 ld-linux.so.2, the dynamical linker, adds shared libraries to the memoryspace of a program to be started. Its flexibility allows for some environment variables to influence the linking process such as preloading shared libraries as well as defining the path in which the linker will search for the shared libraries. Special care must be exercised when runtime-linking setuid- or setgid-binaries: The runtime-linker must not link against user-specified libraries since the code therein would then run with the elevated privileges of the suid binary. The runtime-linker as used in the SuSE distributions ignores the content of the critical environment variables if the specified path begins with a slash ("/"), or if the library file name is not cached (eg it is contained in a path from /etc/ld.so.conf). However, Solar Designer has found out that even preloading glibc- native shared libraries can be dangerous: The code in the user-linked library is not aware of the fact that the binary runs with suid or sgid privileges. Using debugging features of the glibc (and possibly other features) it is possible for a local attacker to overwrite arbitrary files with the elevated privileges of the suid/sgid binary executed. This may lead to a local root compromise. To eliminate these problems, we provide update packages that completely disregard the LD_* variables upon runtime-linking of a binary that has an effective uid different from the caller's userid. 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. SPECIAL INSTALL INSTRUCTIONS: ============================== The glibc (the shlibs package) is an intrinsic part of the GNU/Linux operating system since most binary executables are dependent on the shared libraries from that package. For this reason, special care must be taken while updating the shlibs package. After downloading the binary rpm files, make sure that your system is idle by bringing it down to Single User Mode (`init 1Ž). If this is not applicable for operational reasons, then keep your machine as calm as possible while you perform the update. In particular, make sure that no shell scripts are running during the update. Install the package using the command rpm -Uhv package-rpm-file Do _NOT_ interrupt the operation of the rpm command! After the installation, execute the commands ldconfig # alternatively, use SuSEconfig /sbin/init u # will restart init At this point, the update is done. On low-memory machines a reboot is advisable to free the memory that is used by the old memory-mapped libraries. Note 1: The upcoming SuSE-7.1 distribution is based on glibc-2.2. This distribution is not affected by the security problems in glibc as discussed in security forums. Note 2: The source rpm for the shlibs package is called "libc*.rpm". Multiple binary rpm packages are being generated from this source rpm package. These include: localedb, nssv1, shlibs, timezone. To get a fix for the runtime-linker related security issue (topic of this announcement), it is only necessary to update the shlibs binary rpm package.
