-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: kernel Announcement ID: SUSE-SA:2009:046 Date: Fri, 28 Aug 2009 11:00:00 +0000 Affected Products: SUSE SLES 9 Novell Linux Desktop 9 Open Enterprise Server Novell Linux POS 9 SLE SDK 10 SP2 SUSE Linux Enterprise Desktop 10 SP2 SUSE Linux Enterprise 10 SP2 DEBUGINFO SUSE Linux Enterprise Server 10 SP2 Vulnerability Type: local privilege escalation Severity (1-10): 7 SUSE Default Package: yes Cross-References: CVE-2009-2698 Content of This Advisory: 1) Security Vulnerability Resolved: Linux kernel security update Problem Description 2) Solution or Work-Around 3) Special Instructions and Notes 4) Package Location and Checksums 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report. 6) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Problem Description and Brief Discussion A single critical security issues was fixed in the SUSE Linux Enterprise 9 and 10 kernels, which allowed local users to gain root privileges. The issue is tracked by CVE-2009-2698 and is a missing check in the MSG_PROBE socket handling of IPv4 and IPv6 sockets. This bug was fixed in the 2.6.18 upstream kernel but was not deemed security relevant at that time. This means that SUSE Linux Enterprise 11 products and openSUSE products are not affected. We wish to thank Tavis Ormandy, who pointed out that this problem is yet another NULL page code execution problem. No other bugs were fixed in this update. 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 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 <file.rpm> to apply the update, replacing <file.rpm> 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 10 SP2 for AMD64 and Intel EM64T

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 <file> replacing <file> with the name of the file where you saved 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 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 <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 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. To subscribe, send an e-mail to <opensuse-security-announce+subscribe@opensuse.org>. ===================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>.
