The SUSE Security Summary Reports do not list md5 sums or download URLs like the SUSE Security Announcements that are released for more severe vulnerabilities. Fixed packages for the following incidents are already available on our FTP server and via the YaST Online Update. - SUSE Linux 8.2 discontinued As previously announced we have discontinued support of SUSE Linux 8.2 on the 31rd of July. Begin of next week we will now move away the directories for the YaST Online Update to free disk space on the mirrors. The YOU patches and fixed RPMs will remain on: ftp://ftp.suse.com/pub/suse/discontinued/i386/8.2/ - pstopnm use of ghostscript without -dSAFER pstopnm in netpbm does not properly use the "-dSAFER" option when calling Ghostscript to convert convert a Postscript file into a (1) PBM, (2) PGM, or (3) PNM file, which allows external user-complicit attackers to execute arbitrary commands. This is tracked by the Mitre CVE ID CAN-2005-2471. This problem affects all SUSE Linux based products. - gaim various security problems Various memory corruption bugs within the GNOME instant messenger client gaim have been fixed: - An AIM/ICQ malformed filename crash. Mitre CVE ID: CAN-2005-2102 - - An AIM/ICQ away-message buffer overflow. Mitre CVE ID: CAN-2005-2103 For the SUSE Linux 9.3 and 9.2 distributions a memory alignment bug within libgadu has been fixed too, tracked by the Mitre CVE ID CAN-2005-1852. All SUSE Linux versions including gaim are affected. - kopete gadu denial of service attack The KDE instant messenging program 'kopete' was affected by a problem within the "gadu" protocol handling. A specially crafted 'gadu' message could crash the program. This is tracked by the Mitre CVE ID CAN-2005-1852. Only SUSE Linux 9.3 contained the vulnerable code, no other versions were affected. - squirrelmail various cross site scripting issues The web mailer squirrelmail had several more cross site scripting problems which were fixed upstream. This patch integrates them into our packages. This is tracked by the Mitre CVE ID CAN-2004-0519. This issue affects SUSE Linux Professional 9.0 up to 9.3. - awstats remote code execution The web statistics program 'awstats' contains an invalid usage of the eval() function within the awstats perl script. This vulnerability can be used by remote attackers to execute arbitrary code. This issue is tracked by the Mitre CVE ID CAN-2005-1527 and affects SUSE Linux 9.0 up to 9.3. - powerdns denial of service attack The PowerDNS nameserver was updated to fix the following security issues: - The LDAP backend could fail and not respond anymore. This is tracked by the Mitre CVE ID CAN-2005-2301. - Recursive Queries of unauthorized clients could temporarily block queries of authorized clients. This is tracked by the Mitre CVE ID CAN-2005-2302. Only SUSE Linux 9.3 contains the pdns package and is affected. - gpdf and kpdf denial of service attack Broken as well as specially crafted PDF files can cause the GNOME PDF viewer gpdf and the KDE PDF viewer PDF to create large files in /tmp until the filesystem runs out of space. This is tracked by the Mitre CVE ID CAN-2005-2097. Only gpdf and kpdf in SUSE Linux 9.3 are affected by this problem. - MediaWiki cross site scripting problem Several cross site scripting (XSS) bugs were found and fixed in MediaWiki. - in the page move template, tracked by the Mitre CVE ID CAN-2005-2215. - with HTML attributes In page templates, tracked by the Mitre CVE ID CAN-2005-1888. Only SUSE Linux 9.3 includes MediaWiki and is affected by this problem. - wipe left around backup copies Due to bad path handling the secure file deletion tool 'wipe' in some cases leaves around a copy of the original file. This problem affects SUSE Linux 9.1 up to 9.3. - ethereal various security issues This update upgrades ethereal to version 0.10.12 which has all known security bugs fixed. Bugs fixed are tracked by the Mitre CVE IDs CAN-2005-2360, CAN-2005-2361, CAN-2005-2362, CAN-2005-2363, CAN-2005-2364, CAN-2005-2365, CAN-2005-2366, and CAN-2005-2367. A detailed list of bugs fixed can be found at: http://ethereal.com/appnotes/enpa-sa-00020.html All SUSE Linux versions were affected by this problem. ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds - acroread plugin buffer overflow A buffer overflow was reported in the Acrobat Reader plugin, allowing remote attackers to potentially execute code as the viewing user. This is tracked by the Mitre CVE ID CAN-2005-2470, we are currently testing updates. - various kernel security issues We are currently preparing a security kernel update for the 2.6 lines of kernels fixing currently known issues. We expect it to be released end of next week. - evolution format string problems Format string problems were reported in the evolution mail client. We are preparing updates for this issue. ______________________________________________________________________________ 3) Authenticity Verification and Additional Information - Announcement authenticity verification: SUSE security announcements are published via mailing lists and on Web sites. The authenticity and integrity of a SUSE security announcement is guaranteed by a cryptographic signature in each announcement. All SUSE security announcements are published with a valid signature. To verify the signature of the announcement, save it as text into a file and run the command gpg --verify <file> replacing <file> with the name of the file containing the announcement. The output for a valid signature looks like: gpg: Signature made <DATE> using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team <security@suse.de>" where <DATE> is replaced by the date the document was signed. If the security team's key is not contained in your key ring, you can import it from the first installation CD. To import the key, use the command gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc - Package authenticity verification: SUSE update packages are available on many mirror FTP servers all over the world. While this service is considered valuable and important to the free and open source software community, the authenticity and integrity of a package needs to be verified to ensure that it has not been tampered with. The internal 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, replacing <file.rpm> with the filename of the RPM package downloaded. The package is unmodified if it contains a valid signature from build@suse.de with the key ID 9C800ACA. This key is automatically imported into the RPM database (on RPMv4-based distributions) and the gpg key ring of 'root' during installation. You can also find it on the first installation CD and included at the end of this announcement. - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - General Linux and SUSE security discussion.
