-----BEGIN PGP SIGNED MESSAGE----- ISS and the OpenSSH team just released advisories concerning the OpenSSH vulnerability. These advisories state that the vulnerability exists only if the package has been compiled with support for S/Key or BSDAUTH authentication. Inspecting the patches included in the OpenSSH advisory however show that there is a second vulnerability that can be exploited when interactive keyboard mode is enabled (via the PAMAuthenticationViaKbdInt option in sshd_config). Neither S/Key or BSDAUTH were enabled in previous RPMs released by SuSE (i.e. the OpenSSH 2.9.9p2 RPMs previously released on March 6, and the OpenSSH 3.0.2p1 RPMs released with SuSE Linux 8.0). Support for interactive keyboard mode is compiled in, and is off by default in recent RPMs. However, it can be enabled by the administrator. Which means that, in the default configuration, SuSE Linux users are not affected by this vulnerability. We will release another set of RPMs that fix this vulnerability soon. -----BEGIN PGP SIGNATURE----- Version: 2.6.3in Charset: noconv iQEVAwUBPRoAK3ey5gA9JdPZAQGPYwf+LM2z48HlQLHZBkKcKKjJPHyxVlK4JcFs vqyfcXTgXpjw1ja4NAZpYipMTCHC46IRVjiWHOxKTku2fyUjWe/w3/HdBnY7C51m Un2O7/LcxUrCLipnz6M8c+RzGoWbLQlne0Q8ohPkEcIIOIGBzVYQ+eHjKVY4QYDy +bCA/I+DhsS1QVmdgysNGWjuTd3oiUCYypb1ICLDhE2H0lD3su/HHzhJbFn+lT/a SKqlAwlYGcnL0+776gz1hx084uHKI29BvRaFDmtQ9MVbfDG/Tc/DqqtskPxtSsLL ZkvdPLyQOTjLxZkp7BBDH+1NSim+7t9xiYw8T2kYSsnRlZm8BreOlA== =LoIo -----END PGP SIGNATURE-----

SuSE Security Announcement: OpenSSH (SuSE-SA:2002:023)

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: openssh Announcement-ID: SuSE-SA:2002:023 Date: Tue Jun 25 2002 Affected products: 6.4, 7.0, 7.1, 7.2, 7.3, 8.0 SuSE Linux Database Server, SuSE eMail Server III, SuSE Linux Enterprise Server, SuSE Linux Firewall on CD Vulnerability Type: unknown Severity (1-10): 9 SuSE default package: yes Content of this advisory: 1) security vulnerability resolved: unknown vulnerability in the OpenSSH daemon. 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 There's a new vulnerabilty in the OpenSSH daemon, of which we were notified yesterday. The OpenSSH/OpenBSD team has asked Linux vendors to upgrade their platforms to OpenSSH 3.3, and change the configuration to use the relatively new "Privilege Separation" code. According to their information, 3.3 does not fix the vulnerability, but using privilege separation prevents exploits. We were not given any additional information on the nature of the vulnerability. Setting PrivilegeSeparation to on causes large portions of the daemon to run in a so-called "chroot jail", i.e. in a very restricted environment. An attacker breaking this part of the SSH daemon will *not* obtain full root privilege (as he would if sshd ran without this option), but will find himself in an empty directory, inside a process running as a non privileged user (he can still do some harm this way, but it's a far cry from full root powers). The SuSE security team has prepared RPMs that upgrade OpenSSH to version 3.3p1 on all SuSE Linux platforms. Based on the information we've been given, we are unable to provide updates containing a complete fix, nor can we guarantee that the workaround using privilege separation is enough to protect you. Given these imponderabilities, we suggest to you to take additional precautions until details of the vulnerability have been published, and we have been able to assess it: - if you do not need external access to your SSH daemons, turn off the SSH service on these machine completely, or block external access at the firewall. - if you do need external access to your SSH daemons, make sure you restrict the hosts that it will talk to by setting appropriate firewall rules. If, for some reason, you cannot configure your firewall to block external SSH access, you can also restrict access through /etc/hosts.allow; the following will allow connections from hosts with IP addresses 1.2.3.4, from hosts on the clas C IP network 192.168.5.0, and from hosts in the foo.net DNS domain, while rejecting any other connections. sshd : 1.2.3.4 : allow sshd : 192.168.5.0/255.255.255.0 : allow sshd : *.foo.net : allow sshd : ALL : deny As soon as we are given the relevant details, the SuSE security team will publish a follow-up advisory, and another openssh update, as required. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. If you are running nscd (enabled by default since SuSE Linux 7.0), the name service caching daemon, shut down the daemon prior to upgrading (this works around a bug in the groupadd command): rcnscd stop Then, install the package using the following command to apply the update: rpm -Fvh openssh*.rpm After upgrading, please restart the SSH server by executing the following command as super user: rcsshd restart Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. Special notice concerning SuSE Linux 6.4 and 7.0: SuSE Linux 6.4 ceased to be supported a week or two ago. However, given the potential impact of this problem, we decided to issue update packages for 6.4 as well. These are in the process of getting built, and will show up on our FTP server soon. Users of SuSE Linux 6.4 and 7.0, please also note that crypto update packages for these platforms are always made available through ftp.suse.de only, not ftp.suse.com, due to the crypto laws that were in effect in the US at the time of the original release of the product. i386 Intel Platform SuSE-8.0 ftp://ftp.suse.com/pub/suse/i386/update/8.0/sec1/openssh-3.3p1-6.i386.patch… aa29ca8bcedf674605c69d3ebb20456c ftp://ftp.suse.com/pub/suse/i386/update/8.0/sec1/openssh-3.3p1-6.i386.rpm 568b475b982721e62f557557c59624fb source rpm: ftp://ftp.suse.com/pub/suse/i386/update/8.0/zq1/openssh-3.3p1-6.src.rpm 5a533bd017d86346986904b0c9e6c3e5 SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/sec1/openssh-3.3p1-6.i386.rpm 86b3182d742afba08a99bb04ae91f70f source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.3/zq1/openssh-3.3p1-6.src.rpm 4d017a1b4a49d0da63ca18c817961b48 SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/sec1/openssh-3.3p1-6.i386.rpm d559ad7d04162a32c58fa07b480be820 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/openssh-3.3p1-6.src.rpm 90a4577e90d31ab9c393269c94f4fe86 SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/sec1/openssh-3.3p1-6.i386.rpm 3f5999291e0959ebbc1afbd152d3b1f0 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/openssh-3.3p1-6.src.rpm 73c1b72c4616253d8292fad76ef0b41b SuSE-7.0 ftp://ftp.suse.de/pub/suse/i386/update/7.0/sec1/openssh-3.3p1-6.i386.rpm b670aa96ceaa97a33cd4b2009492e1ea source rpm: ftp://ftp.suse.de/pub/suse/i386/update/7.0/zq1/openssh-3.3p1-6.src.rpm 8f77876f90ef86a2e6fb8e23c34fbd6f Sparc Platform SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/sec1/openssh-3.3p1-4.sparc.rpm d1306f869119e076bcb1693d8de837e4 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.3/zq1/openssh-3.3p1-4.src.rpm 6495e65b671b788cb62f8dcfd7f81f45 SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/sec1/openssh-3.3p1-4.sparc.rpm ae8c8de1505ed2ac56fc5ec20041819c source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/openssh-3.3p1-4.src.rpm 16425d92da3c9fa9feeee0322a216b1b SuSE-7.0 ftp://ftp.suse.de/pub/suse/sparc/update/7.0/sec1/openssh-3.3p1-4.sparc.rpm 05a40abfdbd42b5465e367a187a3393c source rpm: ftp://ftp.suse.de/pub/suse/sparc/update/7.0/zq1/openssh-3.3p1-4.src.rpm bf000a597b2cc3b33517887fa50f0504 AXP Alpha Platform SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/sec1/openssh-3.3p1-4.alpha.rpm 478503f40c0ef3ed2d5b3ea40dd74e32 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/openssh-3.3p1-4.src.rpm e8b93a73622386a95497d0418d2bfa50 SuSE-7.0 ftp://ftp.suse.de/pub/suse/axp/update/7.0/sec1/openssh-3.3p1-4.alpha.rpm 3001c656fb57915c4bb5dcd5fa8de76d source rpm: ftp://ftp.suse.de/pub/suse/axp/update/7.0/zq1/openssh-3.3p1-4.src.rpm 2fd9646fa24b5298d37a79902230c826 PPC Power PC Platform SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/sec1/openssh-3.3p1-4.ppc.rpm 77dd425d361dc084bad50feefdf1f94c source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.3/zq1/openssh-3.3p1-4.src.rpm 8a928dc956cd107ee91d72fe4b4a8bc6 SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/sec1/openssh-3.3p1-4.ppc.rpm ddbc79c387273ddd0da636c7df951c85 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/openssh-3.3p1-4.src.rpm ef9f5de04c632490fe77b96e06892f01 SuSE-7.0 ftp://ftp.suse.de/pub/suse/ppc/update/7.0/sec1/openssh-3.3p1-4.ppc.rpm 67867b11cefc77dca95aaeb130012507 source rpm: ftp://ftp.suse.de/pub/suse/ppc/update/7.0/zq1/openssh-3.3p1-4.src.rpm 76e2f4d9fb52cc5c7220f52108614542 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - mozilla Cross-dependencies between mozilla and other packages in SuSE Linux products keep us from providing version upgrades for the mozilla packages. Fixing security bugs in our packages is usually done by adding the necessary patches to the existing version to ensure the compatibility and consistency that is expected from our products. In some cases (as with the mozilla package) the complexity of the issue does not allow to add patches any more. By consequence, security related issues in mozilla cannot be addressed. As a service to our user community, we provide packages of newer mozilla versions at ftp://ftp.suse.com/pub/projects/mozilla/. These packages have been verified to run fine; they are not located in the update directory of the distribution in question because we cannot make any claims about the compatibility with the other packages in the product. Security-aware users are encouraged to install the packages from the projects/ directory. - ghostscript RedHat released a security announcement concerning a problem in ghostscript, which could be exploited to gain privilege of the print server user. We are investigating whether SuSE Linux is affected. - kernel netfilter update we are in the process of preparing a kernel update that will include a security fix for a minor netfilter bug. - fetchmail we are in the process of releasing a security update for fetchmail that corrects a vulnerability that could be exploited by hostile mail servers. ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an 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. All SuSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe(a)suse.com>. suse-security-announce(a)suse.com - SuSE's announce-only mailing list.

OpenSSH Vulnerability
by Olaf Kirch 25 Jun '02

25 Jun '02

-----BEGIN PGP SIGNED MESSAGE----- There's a new vulnerabiltiy in the OpenSSH daemon. The OpenSSH/OpenBSD team does not release any details concerning this issue, except: - This bug still exists in the most recent version, 3.3 - They are asking all users to upgrade to version 3.3 (sic), and enable the PrivilegeSeparation option. Setting PrivilegeSeparation to on causes large portions of the daemon to run in a so-called "chroot jail", i.e. in a very restricted environment. An attacker breaking this part of the SSH daemon will *not* obtain full root privilege (as he would if sshd runs without this option), but will find himself in an empty directory, inside a process running as a non privileged user (he can still do some harm this way, but it's a far cry from full root powers, of course). In a posting to bugtraq, Theo de Raadt says that using privilege separation, this new vulnerability cannot be exploited. The SuSE security team is working on creating OpenSSH updates with privilege separation enabled, and testing this functionality. We will release updated RPMs on FTP as they become available. In the meanwhile, we suggest that - if you do not need external access to your SSH daemons, turn off the SSH service on these machine completely, or block external access at the firewall. - if you do need extern access to your SSH daemons, make sure you restrict the hosts that it will talk to by setting appropriate firewall rules. If, for some reason, you cannot configure your firewall to block external SSH access, you can also restrict access through /etc/hosts.allow; the following will allow connections from hosts with IP addresses 1.2.3.4 and 5.6.7.8 while disallowing any other connections. sshd : 1.2.3.4 : allow sshd : 5.6.7.8 : allow sshd : ALL : deny It is not clear however whether this is really effective because we do not know anything about the vulnerability at all.

SuSE Security Announcement: Apache (SuSE-SA:2002:022)

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: apache Announcement-ID: SuSE-SA:2002:022 Date: Tue Jun 18 2002 Affected products: 6.4, 7.0, 7.1, 7.2, 7.3, 8.0 SuSE Linux Database Server, SuSE eMail Server III, SuSE Linux Enterprise Server Vulnerability Type: buffer overflow Severity (1-10): 6 SuSE default package: 6.4 and 7.0: Yes; otherwise: No. Content of this advisory: 1) security vulnerability resolved: buffer overflow in httpd 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 There is a bug in the way the Apache web server handles HTTP requests that use "chunked mode". Chunked mode is a HTTP 1.1 feature that allows a client to send data as a sequence of chunks rather than en bloc. This is useful if it doesn't know the overall length of the content at the time it starts transmitting. Previous versions of apache did not properly detect incorrectly encoded chunks, which caused a buffer overflow on the stack. On 32bit architectures, this overflow cannot be exploited to inject code into the httpd process and gain access to the machine, because the overflow will always result in a segmentation fault, and the process will terminate. On 64bit architectures, it may be possible for an attacker to a exploit the buffer overflow to execute arbitary code with the privileges of the httpd process (user wwwrun on SuSE Linux). Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the following command to apply the update: rpm --nodeps -Fvh apache*.rpm mod_ssl*.rpm If you have modified the configuration file /etc/httpd/httpd.conf, upgrading will backup this file to /etc/httpd/httpd.conf.rpmsave. If this is the case, make sure to restore this backup file. Finally, restart the web server using /usr/sbin/rcapache restart. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. The SuSE security team wishes to thank Mark Cox for advance notification on this issue. For additional information, please refer to http://httpd.apache.org/info/security_bulletin_20020617.txt Due to heat problems, we were not able to build the update packages on all architectures. As soon as possible, we will make update packages for the remaining platforms available on our FTP site. i386 Intel Platform: SuSE-8.0 ftp://ftp.suse.com/pub/suse/i386/update/8.0/n2/apache-1.3.23-120.i386.patch… 58752b3a35523263428c325b340c9ae8 ftp://ftp.suse.com/pub/suse/i386/update/8.0/n2/apache-1.3.23-120.i386.rpm b52837fe3f8512155ae93f7462526841 ftp://ftp.suse.com/pub/suse/i386/update/8.0/n3/apache-devel-1.3.23-120.i386… f55f34491ea29aa6d534ffe9b0210ede ftp://ftp.suse.com/pub/suse/i386/update/8.0/n3/apache-devel-1.3.23-120.i386… 62bffd68432349aef7e025cfc6b24daa ftp://ftp.suse.com/pub/suse/i386/update/8.0/n3/apache-doc-1.3.23-120.i386.p… 5b3af92583dcd86144a045b6bf84c47e ftp://ftp.suse.com/pub/suse/i386/update/8.0/n3/apache-doc-1.3.23-120.i386.r… d95ff5cc4c7810da14bcb8f1cb3e57e8 ftp://ftp.suse.com/pub/suse/i386/update/8.0/sec2/mod_ssl-2.8.7-88.i386.patc… 47aa0feb28b75f31acec281ee39252be ftp://ftp.suse.com/pub/suse/i386/update/8.0/sec2/mod_ssl-2.8.7-88.i386.rpm e6da73d9cd8d7bd270714ff9b39d6b53 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/8.0/zq1/apache-1.3.23-120.src.rpm e1282aa0b6e691f7f30e87578699677c SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n2/apache-1.3.20-66.i386.rpm 99162fb48a80c55639d027d5474c11cc ftp://ftp.suse.com/pub/suse/i386/update/7.3/n2/apache-devel-1.3.20-66.i386.… 10e46a9803cd4e75cbba3633a585e1bb ftp://ftp.suse.com/pub/suse/i386/update/7.3/n2/apache-doc-1.3.20-66.i386.rpm 557dfb6d2f3630d97df0edf22d9fdd17 ftp://ftp.suse.com/pub/suse/i386/update/7.3/sec2/mod_ssl-2.8.4-66.i386.rpm b75dd8a50cd80fd8da3eff201b3ee457 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.3/zq1/apache-1.3.20-66.src.rpm 660d7a2bc270b7dd85f56c20b4690115 SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n2/apache-1.3.19-116.i386.rpm f0970f90132c41cc4af0ae1c315d1e29 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n2/apache-devel-1.3.19-116.i386… 92dc6842465be42dd0a957becd0f1100 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n2/apache-doc-1.3.19-116.i386.r… 224735b838274f7bef5ed01b9f829561 ftp://ftp.suse.com/pub/suse/i386/update/7.2/sec2/mod_ssl-2.8.3-56.i386.rpm b48cb9c0809e05b1e1333a55b108632f source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/apache-1.3.19-116.src.rpm 481c7ff778550f9dc5228be61f91931c SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n2/apache-1.3.19-115.i386.rpm b1fd3fa8c69b1349d99904aa6b99e9a8 ftp://ftp.suse.com/pub/suse/i386/update/7.1/sec2/mod_ssl-2.8.1-0.i386.rpm 81d80d00691f65f377ca84651e88cd95 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/apache-1.3.19-115.src.rpm 37c0af5349df6a3d3cb88a5e192275ec SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/n1/apache-1.3.19-115.i386.rpm 68e855110449a083ede78566cb6a5b88 ftp://ftp.suse.de/pub/suse/i386/update/7.0/sec1/mod_ssl-2.8.2-33.i386.rpm 7eb43089d2d98e8c3349ce4aed592eb2 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/apache-1.3.19-115.src.rpm c30cc941ac035733395e9d481f3b4e57 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/n1/apache-1.3.19-115.i386.rpm 1b11876c0ee94ff754a23d514484881f ftp://ftp.suse.de/pub/suse/i386/update/6.4/sec1/mod_ssl-2.8.1-0.i386.rpm 1d4201fc49562e9fadb9d7305c2e6a1f source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/apache-1.3.19-115.src.rpm 3475601e8a2965c3881fc4a1f7f7c059 PPC Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n2/apache-1.3.20-52.ppc.rpm 2a0b2f39c6125ea3746463a22cba969a ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n2/apache-devel-1.3.20-52.ppc.rpm d0c224aa4bed25323c7411c93a6a7dc9 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n2/apache-doc-1.3.20-52.ppc.rpm ff36210534c8dc01f446d98b9d64db7d ftp://ftp.suse.com/pub/suse/ppc/update/7.3/sec2/mod_ssl-2.8.4-52.ppc.rpm d69d377d5d3d1e8dcbabe639e28dc891 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.3/zq1/apache-1.3.20-52.src.rpm 311821ffad1c8a00299e019e23c8d869 SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/n2/apache-1.3.19-56.ppc.rpm ecbee32eecfe72c072af6c18c37427f4 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/sec2/mod_ssl-2.8.1-0.ppc.rpm 4172e8b5ca7282382c7737354189f4e8 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/apache-1.3.19-56.src.rpm d133f180b66d191d6167f55e0d010c54 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/n1/apache-1.3.19-56.ppc.rpm ea9d2b6134bd916b6aab2c02fedb5037 ftp://ftp.suse.de/pub/suse/ppc/update/7.0/sec1/mod_ssl-2.8.2-15.ppc.rpm 3b05ef7a9b2cd4e32e29c1b2f3f472e4 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/apache-1.3.19-56.src.rpm db5283dbf5b943724630b4d50441f17c SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/n1/apache-1.3.19-56.ppc.rpm ab9e840afdc3ef4c8a74583ffe2d99b4 ftp://ftp.suse.de/pub/suse/ppc/update/6.4/sec1/mod_ssl-2.8.1-0.ppc.rpm 2ae0751a1b8fad7f3cba97a4ed4d568e source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/apache-1.3.19-56.src.rpm cbe2e9b6b4e10411cc71ee5817cc2ef5 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - mozilla Cross-dependencies between mozilla and other packages in SuSE Linux products keep us from providing version upgrades for the mozilla packages. Fixing security bugs in our packages is usually done by adding the necessary patches to the existing version to ensure the compatibility and consistency that is expected from our products. In some cases (as with the mozilla package) the complexity of the issue does not allow to add patches any more. By consequence, security related issues in mozilla cannot be addressed. As a service to our user community, we provide packages of newer mozilla versions at ftp://ftp.suse.com/pub/projects/mozilla/. These packages have been verified to run fine; they are not located in the update directory of the distribution in question because we cannot make any claims about the compatibility with the other packages in the product. Security-aware users are encouraged to install the packages from the projects/ directory. - ghostscript RedHat released a security announcement concerning a problem in ghostscript, which could be exploited to gain privilege of the print server user. We are investigating whether SuSE Linux is affected. - kernel netfilter update we are in the process of preparing a kernel update that will include a security fix for a minor netfilter bug. - fetchmail we are in the process of releasing a security update for fetchmail that corrects a vulnerability that could be exploited by hostile mail servers. ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an 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.

Supported Distributions
by Roman Drahtmueller 10 Jun '02

10 Jun '02

-----BEGIN PGP SIGNED MESSAGE----- Dear suse-security-announce subscriber, With the release of the SuSE Linux 8.0 i386 ftp version, we announce that the SuSE Linux 6.4 distribution will be discontinued. The high quality standard at SuSE and new features necessary for ftp support required extensive testing of the SuSE Linux 8.0 i386 ftp version. We regret the delay that was the result. Vulnerabilities found after Monday, June 17 2002, will not receive a fix for SuSE Linux 6.4 any more. After two years of successful use, SuSE Linux 6.4 will free resources for the newly released products. By consequence, the 6.4 distributions directories on the ftp server have been moved to the discontinued directory structure; the 6.4 directories in the update trees will follow near the end of the month, soon after all update packages have been published. 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. As usual, SuSE will continue to provide update packages for the remaining distributions SuSE-7.0 SuSE-7.1 SuSE-7.2 SuSE-7.3 and SuSE-8.0 for a two-year period after the release of the respective distribution. Our SLES (SuSE Linux Enterprise Server) products and the patches support for them are not affected by this announcement. If you have any questions regarding this announcement, please send email to security(a)suse.de (primary security contact). Regards, Roman Drahtmüller, SuSE Security. - -- - - | Roman Drahtmüller <draht(a)suse.de> // "You don't need eyes to see, | SuSE Linux AG - Security Phone: // you need vision!" | Nürnberg, Germany +49-911-740530 // Maxi Jazz, Faithless | - - -----BEGIN PGP SIGNATURE----- Version: 2.6.3i Charset: noconv iQEVAwUBPQUf/Hey5gA9JdPZAQETtgf+MElVghYqHZd8up8rbID3+Ovw0a8U+kjQ WZpmnD4wWOycNyTBHeh0ial8y66GWL3LeTzLd6U3n3tpU8cklb6js5nMlUHOI85L y1M9qV/L332GfChcDmuEkPSvmrNyISEsqTHer6u/3HdXsT6epEJLu9Y0lr8Kihg6 INU+ww2HBtldlfjszEACLJdHzHo9vbMI5yg8t/d52/5b8h4zB9lsOawq1SNQpUpi JiYT1S3u6K9dydGdXMPgBt2N9QWKJc2sgvg80NeKumvA6ZHuGpwBUybmHSnqjY+T ScegNfAd3w5nYdigzZowZNRCNV5BMTnEmvwlDgBFgBuwscUuFMMHrQ== =nZp1 -----END PGP SIGNATURE-----

SuSE Security Announcement: bind9/bind9-beta (SuSE-SA:2002:021)
by Roman Drahtmueller 06 Jun '02

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: bind9, bind9-beta Announcement-ID: SuSE-SA:2002:021 Date: Thursday, Jun 6th, 02:00 MEST 2002 Affected products: 7.0, 7.1, 7.2, 7.3, 8.0 Vulnerability Type: remote denial of service attack Severity (1-10): 4 SuSE default package: no Other affected systems: systems running ISC bind9 Content of this advisory: 1) security vulnerability resolved: bind9 NAPTR bug 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 There is a bug in the BIND9 name server that is triggered when processing certain types of DNS replies. When this happens an assertion will fail, and named will log a message to the system log before exiting. This means a remote attacker can easily shut down the name server process. This bug has been fixed using a patch provided by ISC via CERT. Since there is no workaround to this problem, we recommend that all users of bind9 update to the new packages. Note that on SuSE 7.1 and later, it is not sufficient to update the bind9 package itself; the vulnerability occurs in a shared library included in the bind9-utils package. Please also note that SuSE Linux after and including 7.3 contain two different bind9 packages: One called bind9 with its subpackages, and one called bind9-beta, also with subpackages. Use the command rpm -qa|grep bind9 to find out which version of bind9 is installed on your system. We recommend to run a non-beta version of bind9 on production systems. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. i386 Intel Platform: SuSE-8.0 ftp://ftp.suse.com/pub/suse/i386/update/8.0/n4/bind9-9.1.3-197.i386.rpm

______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - slurp - in a posting to bugtraq, a vulnerability in an NNTP news client named slurp was reported. slurp should not be confused with "slurpd", which is part of the openldap/openldap2 package. SuSE does not ship slurp, the news client, and is therefore not vulnerable. - ghostscript - RedHat Security released an announcement concerning a problem in ghostscript, which could be exploited to gain the privileges of the print server user. We are investigating whether SuSE Linux is affected. - kernel netfilter update - we are in the process of preparing a kernel update that will include a security fix for a minor netfilter bug. - fetchmail - we are in the process of releasing a security update for fetchmail that corrects a vulnerability that could be exploited by hostile mail servers. - Update packages for KDE-3.0.1 to make the transition from KDE-3.0 for the SuSE Linux 8.0-i386 distribution can be found at the usual path on our ftp server ftp.suse.com, also available through our online update utility YOU. These packages have now been replaced to fix two vulnerabilities in khtml. One of them is similar to the "Opera javascript protocoll vulnerability", published by Andreas Sandblad on bugtraq. The weakness allows to inject JavaScript code in a subframe that the parent frame should not have access to. The other problem is of a similar gravity, giving the update a comparatively uncritical magnitude. We wish to express our gratitude to the KDE developers and particularly to Dirk Mueller who fixed this problem instantly. ______________________________________________________________________________ 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. All SuSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe(a)suse.com>. suse-security-announce(a)suse.com - SuSE's announce-only mailing list. Only SuSE's security annoucements are sent to this list. To subscribe, send an email to <suse-security-announce-subscribe(a)suse.com>. For general information or the frequently asked questions (faq) send mail to: <suse-security-info(a)suse.com> or <suse-security-faq(a)suse.com> respectively. ===================================================================== SuSE's security contact is <security(a)suse.com> or <security(a)suse.de>.
