Following security issues were fixed: CVE-2010-3904: A local privilege escalation in RDS sockets allowed local attackers to gain root privileges. CVE-2010-2963: A problem in the compat ioctl handling in video4linux allowed local attackers with a video device plugged in to gain root privileges on x86_64 systems. Please note that the net/rds socket protocol module only lives in the -extra kernel package, which is not installed by default on the SUSE Linux Enterprise Server 11. CVE-2010-2963: A problem in the compat ioctl handling in video4linux allowed local attackers with a video device plugged in to gain privileges on x86_64 systems. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes Please reboot the machine after installing the update. 4) Package Location and Checksums The preferred method for installing security updates is to use the YaST "Online Update" module or the "zypper" commandline tool. The package and patch management stack will detect which updates are required and automatically perform the necessary steps to verify and install them. Alternatively, download the update packages for your distribution manually and verify their integrity by the methods listed in Section 6 of this announcement. Then install the packages using the command rpm -Fhv to apply the update, replacing with the filename of the downloaded RPM package. Our maintenance customers are notified individually. The packages are offered for installation from the maintenance web: SUSE Linux Enterprise Desktop 11 SP1 http://download.novell.com/patch/finder/?keywords=f01275198337ab5cb5d84d49e735536a http://download.novell.com/patch/finder/?keywords=4b53dedac262e9445a17875eb5c427c1 SUSE Linux Enterprise High Availability Extension 11 SP1 http://download.novell.com/patch/finder/?keywords=f01275198337ab5cb5d84d49e735536a http://download.novell.com/patch/finder/?keywords=62e204eb8d1d000a79827a7025517cb0 http://download.novell.com/patch/finder/?keywords=adc9683d6a609c0277de95be53889718 http://download.novell.com/patch/finder/?keywords=eeac7bc3f9cb557c84227f368fc501dd http://download.novell.com/patch/finder/?keywords=4b53dedac262e9445a17875eb5c427c1 SUSE Linux Enterprise Server 11 SP1 http://download.novell.com/patch/finder/?keywords=f01275198337ab5cb5d84d49e735536a http://download.novell.com/patch/finder/?keywords=62e204eb8d1d000a79827a7025517cb0 http://download.novell.com/patch/finder/?keywords=adc9683d6a609c0277de95be53889718 http://download.novell.com/patch/finder/?keywords=eeac7bc3f9cb557c84227f368fc501dd http://download.novell.com/patch/finder/?keywords=4b53dedac262e9445a17875eb5c427c1 http://download.novell.com/patch/finder/?keywords=368f948d6daf9ef617426598410ee91b http://download.novell.com/patch/finder/?keywords=b754e974a6256476bb650664f4a62cee ______________________________________________________________________________ 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report. ______________________________________________________________________________ 6) 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 replacing with the name of the file where you saved the announcement. The output for a valid signature looks like: gpg: Signature made using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team " where 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 the 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 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.
