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. - chmlib buffer overflow A vulnerability was fixed in chmlib and kchmviewer that potentially allowed the execution of arbitrary code. Updates for this issue were released Feb 1st and it is tracked by the Mitre CVE ID CVE-2007-0619. - GraphicsMagick and ImageMagick small problems ImageMagick and GraphicsMagick were updated to fix a broken patch for CVE-2006-5456 and another minor non-security issues. (CVE-2007-0770). - various PDF viewers endless recursion problem All XPDF derived PDF viewers and libraries have been updated to fix a vulnerability which occurs while processing a special PDF file, which can cause endless recursion and a crash by overflowing the stack. Code execution is not considered possible. The issue was found by the Apple Month of Bugs project and is tracked by the Mitre CVE ID CVE-2007-0104. Fixed packages were released for: xpdf, poppler, gpdf, kdegraphics3-pdf, koffice-wordprocessing, libextractor, cups. - pam_unix login problem A bug in pam_unix module allowed users under certain circumstances to log in although their account was locked. pam_unix is not used on openSUSE by default. This issue only affected openSUSE 10.2 and is tracked by the Mitre CVE ID CVE-2007-0003. ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds - Next kernel update We are currently preparing a kernel update for SUSE Linux 10.1 and SUSE Linux Enterprise Server/Desktop 10. The main focus of this update is a bugfix release, but several smaller security issues have been addressed too. - Mozilla Firefox / Thunderbird / SeaMonkey updates New versions of Mozilla Firefox, Thunderbird and SeaMonkey will be released next week, including also security fixes. We will be releasing updates for those new stable versions. - fetchmail security problems The POP3/IMAP client fetchmail had two security issues fixed: - Incorrect SSL handling could allow a man in the middle attack against fetchmail or could expose passwords and similar when too trivial encryption would be selected. (CVE-2006-5867) - A fetchmail daemon might crash when using direct MDA delivery. (CVE-2006-5974) Due to various regressions spotted during QA we were not yet able to release these updates but likely will do so next week. - php 5.2.1 security update A PHP5 security update was released by the PHP team. We are currently preparing updates for the issues fixed in this update. ______________________________________________________________________________ 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: opensuse-security@opensuse.org - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to <opensuse-security+subscribe@opensuse.org>. suse-security-announce@suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to <suse-security-announce-subscribe@suse.com>. ===================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>. The <security@suse.de> public key is listed below. ===================================================================== ______________________________________________________________________________ The information in this advisory may be distributed or reproduced, provided that the advisory is not modified in any way. In particular, the clear text signature should show proof of the authenticity of the text.
