-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: kernel Announcement ID: SUSE-SA:2008:049 Date: Thu, 02 Oct 2008 10:00:00 +0000 Affected Products: SUSE Linux Enterprise Desktop 10 SP1 SUSE Linux Enterprise 10 SP1 DEBUGINFO SLE SDK 10 SP1 SUSE Linux Enterprise Server 10 SP1 Vulnerability Type: remote denial of service Severity (1-10): 7 SUSE Default Package: yes Cross-References: CVE-2008-0598, CVE-2008-1673, CVE-2008-2812 CVE-2008-2931, CVE-2008-3272, CVE-2008-3275 CVE-2008-3525 Content of This Advisory: 1) Security Vulnerability Resolved: Linux kernel 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 The SUSE Linux Enterprise 10 Service Pack 1 kernel was updated to fix lots of bugs and also contains several security fixes: CVE-2008-3525: Added missing capability checks in sbni_ioctl(). CVE-2008-0598: On AMD64 some string operations could leak kernel information into userspace. CVE-2008-1673: Added range checking in ASN.1 handling for the CIFS and SNMP NAT netfilter modules. CVE-2008-3272: Fixed range checking in the snd_seq OSS ioctl, which could be used to leak information from the kernel. CVE-2008-3275: Fixed a memory leak when looking up deleted directories which could be used to run the system out of memory. CVE-2008-2931: The do_change_type function in fs/namespace.c did not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint. CVE-2008-2812: Various NULL ptr checks have been added to tty op functions, which might have been used by local attackers to execute code. We think that this affects only devices openable by root, so the impact is limited. For more information consult the RPM changelog. 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 SP1 for AMD64 and Intel EM64T http://download.novell.com/index.jsp?search=Search&keywords=6bd057f7a4099ff8b490cbbb8a8f1de8 SUSE Linux Enterprise Desktop 10 SP1 http://download.novell.com/index.jsp?search=Search&keywords=6bd057f7a4099ff8b490cbbb8a8f1de8 http://download.novell.com/index.jsp?search=Search&keywords=afe04b0aa9f77bf3d5d2aae664e80aef SUSE Linux Enterprise Desktop 10 SP1 for x86 http://download.novell.com/index.jsp?search=Search&keywords=afe04b0aa9f77bf3d5d2aae664e80aef SUSE Linux Enterprise 10 SP1 DEBUGINFO for IBM zSeries 64bit http://download.novell.com/index.jsp?search=Search&keywords=62d35a4540b189eee1ef8b2cb3ae4349 SUSE Linux Enterprise 10 SP1 DEBUGINFO for IBM POWER http://download.novell.com/index.jsp?search=Search&keywords=f8cf68e6de7a22f3baa12c9fa364351a SUSE Linux Enterprise Server 10 SP1 http://download.novell.com/index.jsp?search=Search&keywords=6bd057f7a4099ff8b490cbbb8a8f1de8 http://download.novell.com/index.jsp?search=Search&keywords=afe04b0aa9f77bf3d5d2aae664e80aef http://download.novell.com/index.jsp?search=Search&keywords=62d35a4540b189eee1ef8b2cb3ae4349 http://download.novell.com/index.jsp?search=Search&keywords=f8cf68e6de7a22f3baa12c9fa364351a http://download.novell.com/index.jsp?search=Search&keywords=fa7f61687e031771e2f5ee59d0cd9bd7 SLE SDK 10 SP1 http://download.novell.com/index.jsp?search=Search&keywords=6bd057f7a4099ff8b490cbbb8a8f1de8 http://download.novell.com/index.jsp?search=Search&keywords=afe04b0aa9f77bf3d5d2aae664e80aef http://download.novell.com/index.jsp?search=Search&keywords=f8cf68e6de7a22f3baa12c9fa364351a http://download.novell.com/index.jsp?search=Search&keywords=fa7f61687e031771e2f5ee59d0cd9bd7 SUSE Linux Enterprise 10 SP1 DEBUGINFO http://download.novell.com/index.jsp?search=Search&keywords=6bd057f7a4099ff8b490cbbb8a8f1de8 http://download.novell.com/index.jsp?search=Search&keywords=afe04b0aa9f77bf3d5d2aae664e80aef http://download.novell.com/index.jsp?search=Search&keywords=f8cf68e6de7a22f3baa12c9fa364351a http://download.novell.com/index.jsp?search=Search&keywords=fa7f61687e031771e2f5ee59d0cd9bd7 SUSE Linux Enterprise 10 SP1 DEBUGINFO for IPF http://download.novell.com/index.jsp?search=Search&keywords=fa7f61687e031771e2f5ee59d0cd9bd7 ______________________________________________________________________________ 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 <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>.
