-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: kernel Announcement ID: SUSE-SA:2008:047 Date: Wed, 01 Oct 2008 13:00:00 +0000 Affected Products: SUSE SLES 9 Novell Linux Desktop 9 Open Enterprise Server Novell Linux POS 9 Vulnerability Type: remote denial of service Severity (1-10): 7 SUSE Default Package: yes Cross-References: CVE-2007-6716, CVE-2008-0598, CVE-2008-1673 CVE-2008-2812, CVE-2008-3272, CVE-2008-3525 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 The Linux kernel in the SUSE Linux Enterprise Server 9 Service Pack 4 was released to fix various bugs and also some security problems: CVE-2007-6716: Zero the struct dio with kzalloc instead of doing it member-wise, this could have leaked information from the kernel. CVE-2008-3525: Added missing capability checks in sbni_ioctl(). CVE-2008-0598: On AMD64 some string operations could leak kernel information into user space. 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-2008-2812: 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. More details are available in the package changelog. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes Please reboot your 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 <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: Open Enterprise Server http://download.novell.com/index.jsp?search=Search&keywords=7f6082d83ebb412cb08a347f1d4f15d4 Novell Linux Desktop 9 for x86 http://download.novell.com/index.jsp?search=Search&keywords=7f6082d83ebb412cb08a347f1d4f15d4 Novell Linux POS 9 http://download.novell.com/index.jsp?search=Search&keywords=cbbe741f8b8b2844954325c7b19640e8 SUSE CORE 9 for x86 http://download.novell.com/index.jsp?search=Search&keywords=cbbe741f8b8b2844954325c7b19640e8 Novell Linux Desktop 9 http://download.novell.com/index.jsp?search=Search&keywords=7f6082d83ebb412cb08a347f1d4f15d4 http://download.novell.com/index.jsp?search=Search&keywords=ab571d638a77193397f7750e6adc1db1 Novell Linux Desktop 9 for x86_64 http://download.novell.com/index.jsp?search=Search&keywords=ab571d638a77193397f7750e6adc1db1 SUSE CORE 9 for IBM POWER http://download.novell.com/index.jsp?search=Search&keywords=a7de9a18ad854efa026811d679868b52 SUSE CORE 9 for AMD64 and Intel EM64T http://download.novell.com/index.jsp?search=Search&keywords=8980e701b12ad4f9c86c7fe931d87bd7 SUSE CORE 9 for IBM zSeries 64bit http://download.novell.com/index.jsp?search=Search&keywords=656a568516f192405b568d6fb399712b SUSE CORE 9 for IBM S/390 31bit http://download.novell.com/index.jsp?search=Search&keywords=2727447879f3a66b9e835ba69837a927 SUSE SLES 9 http://download.novell.com/index.jsp?search=Search&keywords=cbbe741f8b8b2844954325c7b19640e8 http://download.novell.com/index.jsp?search=Search&keywords=a7de9a18ad854efa026811d679868b52 http://download.novell.com/index.jsp?search=Search&keywords=8980e701b12ad4f9c86c7fe931d87bd7 http://download.novell.com/index.jsp?search=Search&keywords=656a568516f192405b568d6fb399712b http://download.novell.com/index.jsp?search=Search&keywords=2727447879f3a66b9e835ba69837a927 http://download.novell.com/index.jsp?search=Search&keywords=16461d7e407e4950ee4e06104be3486e SUSE CORE 9 for Itanium Processor Family http://download.novell.com/index.jsp?search=Search&keywords=16461d7e407e4950ee4e06104be3486e ______________________________________________________________________________ 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>. The <security@suse.de> public key is listed below. ===================================================================== ______________________________________________________________________________ The information in this advisory may be distributed or reproduced, provided that the advisory is not modified in any way.
