-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Summary Report Announcement ID: SUSE-SR:2008:002 Date: Fri, 25 Jan 2008 16:00:00 +0000 Cross-References: CVE-2006-7217, CVE-2007-5339, CVE-2007-5340 CVE-2007-5360, CVE-2007-5848, CVE-2007-5849 CVE-2007-5894, CVE-2007-5902, CVE-2007-5965 CVE-2007-5971, CVE-2007-5972, CVE-2007-6284 CVE-2007-6351, CVE-2007-6352, CVE-2007-6599 CVE-2008-0225, MFSA 2007-29 Content of this advisory: 1) Solved Security Vulnerabilities: - tog-pegasus buffer overflow in authentication - xine rtsp buffer overflows - libxml2 denial of service in UTF8 handling - libqt4 incorrect SSL certificate handling - XFree86/X.Org updates reissued - krb5 various small issues - libexif overflows and denial of service - openafs server denial of service - Apache derby post-authentication denial of service - MozillaThunderbird 1.5.0.14 release - Xen denial of service problems 2) Pending Vulnerabilities, Solutions, and Work-Arounds: - kernel updates in preparation - wireshark 0.99.7 security release - various MySQL security issues - various Apache security problems 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 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. - tog-pegasus buffer overflow in authentication A stack based buffer overflow in local PAM authentication for tog-pegasus could be used by attackers to execute code. (CVE-2007-5360) This package only exists on and was updated for the SUSE Linux Enterprise 10 SDK. - xine rtsp buffer overflows Specially crafted rtsp-Streams could cause a buffer overflow in xine. Attackers could potentially exploit that to execute arbitrary code (CVE-2008-0225). Xine-lib has been updated on all affected distributions. - libxml2 denial of service in UTF8 handling libxml2 contained a DoS condition in xmlCurrentChar()'s UTF-8 processing. CVE-2007-6284 has been assigned to this problem. Updates were released for all SUSE Linux based products. - libqt4 incorrect SSL certificate handling A bug in the QSslSocket class could under certain circumstances lead to incorrect SSL certificates beeing accepted as valid (CVE-2007-5965). This problem only affected openSUSE 10.3. - XFree86/X.Org updates reissued We reissued the previously released X.org and XFree86 packages to fix a regression in the MIT SHM handling, which caused some programs (vlc, eclipse, other SWT programs) to abort. - krb5 various small issues This update fixes multiple vulnerabilities in krb5. It's unlikely that those vulnerabilities can actually be exploited. (CVE-2007-5894, CVE-2007-5902, CVE-2007-5971, CVE-2007-5972) Updates have been released for SUSE Linux Enterprise 10, SUSE Linux 10.1 and openSUSE 10.2, and 10.3. - libexif overflows and denial of service Two bugs in libexif were identified by a Google Security Audit done by Meder Kydyraliev. CVE-2007-6351: Loading EXIF data could be used to cause a infinite recursion and crash CVE-2007-6352: Integer overflows in the thumbnail handler could be used to overflow buffers and potentially execute code or crash a program using libexif. Updates have been released for libexif and libexif5 packages on all distributions. - openafs server denial of service This update fixes a remote denial of service (crash) against the openafs server. (CVE-2007-6599) This problem affected only SUSE Linux 10.1. - Apache derby post-authentication denial of service Apache Derby did not determine schema privilege requirements during the DropSchemaNode bind phase, which allows remote authenticated users to execute arbitrary drop schema statements in SQL authorization mode. (CVE-2006-7217) This update also brings a new requirement of a Java 1.5 JRE. Unfortunately this makes an update for Itanium impossible, so Itanium packages are left out for now. - MozillaThunderbird 1.5.0.14 release Mozilla Thunderbird was brought to security update version 1.5.0.14 on SUSE Linux 10.1 and openSUSE 10.2. Following security problems were fixed: - MFSA 2007-29: Crashes with evidence of memory corruption As part of the Firefox 2.0.0.8 update releases Mozilla developers fixed many bugs to improve the stability of the product. Some of these crashes showed evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code. - CVE-2007-5339 Browser crashes - CVE-2007-5340 JavaScript engine crashes - Xen denial of service problems Various Xen issues have been fixed, two of them security related: - CVE-2007-5906: Xen allowed virtual guest system users to cause a denial of service (hypervisor crash) by using a debug register (DR7) to set certain breakpoints. - CVE-2007-5907: Xen 3.1.1 does not prevent modification of the CR4 TSC from applications, which allows pv guests to cause a denial of service (crash). Updates had already been released for SUSE Linux 10.1, openSUSE 10.3 and SUSE Linux Enterprise Server 10. openSUSE 10.2 updates were now released too. ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds - kernel updates in preparation We are currently preparing kernel security updates for SUSE Linux Enterprise 10, SUSE Linux 10.1 and openSUSE 10.2 and 10.3 to fix various security issues and bugs. They will probably be released mid of next week. - wireshark 0.99.7 security release Multiple bugs were fixed in wireshark 0.99.7, updated packages for these problems are currently in QA. - various MySQL security issues We are currently testing a MySQL update to fix various security issues discovered. - Various Apache security problems Various Apache security problems have been found in the last weeks and we are currently preparing updates for them. ______________________________________________________________________________ 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>. opensuse-security-announce@opensuse.org - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list.
