Following security issues were fixed: CVE-2010-2960: local users could crash the system by causing a NULL deref in the keyctl_session_to_parent() function CVE-2010-2954: local users could crash the system by causing a NULL deref via IRDA sockets CVE-2010-3079: local users could crash the system by causing a NULL deref in ftrace CVE-2010-3078, CVE-2010-3297, CVE-2010-3298, CVE-2010-3081, CVE-2010-3296: several kernel functions could leak kernel stack memory contents CVE-2010-3080: local users could cause dereference of an uninitialized pointer via /dev/sequencer CVE-2010-3310: local users could corrupt kernel heap memory via ROSE sockets CVE-2010-2962: local users could write to any kernel memory location via the i915 GEM ioctl interface Additionally this update restores the compat_alloc_userspace() inline function. 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 (YOU) tool. YOU detects which updates are required and automatically performs 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: SLE 11 SERVER Unsupported Extras http://download.novell.com/patch/finder/?keywords=23049e6a880a8130c629fc3a53164541 http://download.novell.com/patch/finder/?keywords=e4f2129e4fd2f70610c0d52b2451dab3 http://download.novell.com/patch/finder/?keywords=637fdba23c17bf14067ca98699468e56 http://download.novell.com/patch/finder/?keywords=7a1157168c47260397716f39797e5da2 http://download.novell.com/patch/finder/?keywords=2ca576876c9933f94890ab92c9700bfa SUSE Linux Enterprise Server 11 SP1 http://download.novell.com/patch/finder/?keywords=039ba32580d28580329514de944be593 http://download.novell.com/patch/finder/?keywords=0b6dfabf37b6d2b5cada53458079e702 http://download.novell.com/patch/finder/?keywords=5d21a11418f02516ef6ae58f362c1f98 http://download.novell.com/patch/finder/?keywords=a7aa7671029d7a723db42187684cb976 http://download.novell.com/patch/finder/?keywords=a412f327abfdfb030c31be1c37133055 SUSE Linux Enterprise Desktop 11 SP1 http://download.novell.com/patch/finder/?keywords=039ba32580d28580329514de944be593 http://download.novell.com/patch/finder/?keywords=a412f327abfdfb030c31be1c37133055 SUSE Linux Enterprise High Availability Extension 11 SP1 http://download.novell.com/patch/finder/?keywords=039ba32580d28580329514de944be593 http://download.novell.com/patch/finder/?keywords=0b6dfabf37b6d2b5cada53458079e702 http://download.novell.com/patch/finder/?keywords=5d21a11418f02516ef6ae58f362c1f98 http://download.novell.com/patch/finder/?keywords=a7aa7671029d7a723db42187684cb976 http://download.novell.com/patch/finder/?keywords=a412f327abfdfb030c31be1c37133055 ______________________________________________________________________________ 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. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to . ===================================================================== SUSE's security contact is or .
