-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Summary Report Announcement ID: SUSE-SR:2008:012 Date: Fri, 06 Jun 2008 16:00:00 +0000 Cross-References: CVE-2008-0073, CVE-2008-1419, CVE-2008-1420 CVE-2008-1423, CVE-2008-1637, CVE-2008-1686 CVE-2008-1878, CVE-2008-2097, CVE-2008-2142 CVE-2008-2388, CVE-2008-2389 Content of this advisory: 1) Solved Security Vulnerabilities: - xine NSF buffer overflow - xemacs and emacs fast-lock file problems - opensuse-updater tmp problems and off-by-one problems - libvorbis security problems - xine sdpplin_parse overflow - vorbis-tools speex code execution problem - pdns-recursor spoofing problems - openwsman post-auth remote code execution 2) Pending Vulnerabilities, Solutions, and Work-Arounds: - kernel update 3) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Solved Security Vulnerabilities To avoid flooding mailing lists with SUSE Security Announcements for minor issues, SUSE Security releases weekly summary reports for the low profile vulnerability fixes. The SUSE Security Summary Reports do not list 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. - xine NSF buffer overflow Specially crafted NSF files could potentially be exploited to execute arbitrary code (CVE-2008-1878). Specially crafted files or streams could potentially be abused to trick applications that support speex into executing arbitrary code (CVE-2008-1686). Updated packages have been released for all SUSE distributions containing XINE. - xemacs and emacs fast-lock file problems Emacs and Xemacs automatically loaded fast-lock files which allowed local attackers to execute arbitrary code as the user editing the associated files (CVE-2008-2142). Xemacs and Emacs have been updated on all SUSE distributions. - opensuse-updater tmp problems and off-by-one problems The opensuse-updater on openSUSE 10.2 was updated to fix a symlink problem and two off-by-one vulnerabilities. The overflows can be considered no security problem and are tracked by CVE-2008-2388. The symlink flaw could be used by local users to gain unauthorized access to information (like passwords) and is tracked by CVE-2008-2389. Only openSUSE 10.2 was affected by this problem. - libvorbis security problems Several security problems were fixed in libvorbis: CVE-2008-1419 - Division by zero CVE-2008-1420 - integer overflow CVE-2008-1423 - integer overflow libvorbis was updated on all SUSE distributions. - xine sdpplin_parse overflow Xine was updated to fix a bug in the function sdpplin_parse() that allowed remote attackers to access process memory out-of a buffers bound. This vulnerability can be used to execute arbitrary code remotely if successfully exploited. (CVE-2008-0073) Xine was updated on all SUSE distributions. - vorbis-tools speex code execution problem Specially crafted files or streams could potentially be abused to trick applications that support speex into executing arbitrary code (CVE-2008-1686) using vorbis-tools. vorbis-tools was fixed on all SUSE distributions. - pdns-recursor spoofing problems Pdns-recursor was prone to a spoofing vulnerability which could be abused to redirect clients or manipulate data. (CVE-2008-1637) pdns / pdns-recursor is shipped on SUSE Linux 10.1, openSUSE 10.2 and 10.3 and was fixed there. - openwsman post-auth remote code execution Openwsman was updated to provide a fix for the included shttpd web-server to patch a buffer overflow vulnerability in the HTTP request parser. This bug can only be exploited by authenticated users to execute arbitrary code with the privileges of the openwsman/shttp daemon. (CVE-2008-2097) Only openSUSE 10.3 contains openwsman and was fixed. ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds - Linux kernel update We are currently preparing a kernel update for all products to catch up on security problems and bugs found in the last months. ______________________________________________________________________________ 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 " 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 to verify the signature of the package, replacing 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-announce@opensuse.org - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to . ===================================================================== SUSE's security contact is or .
