-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: kernel Announcement ID: SUSE-SA:2009:017 Date: Fri, 03 Apr 2009 12:00:00 +0000 Affected Products: SLE SDK 10 SP2 SUSE Linux Enterprise Desktop 10 SP2 SUSE Linux Enterprise 10 SP2 DEBUGINFO SUSE Linux Enterprise Server 10 SP2 Vulnerability Type: remote denial of service Severity (1-10): 7 SUSE Default Package: yes Cross-References: CVE-2008-1294, CVE-2009-0028, CVE-2009-0065 CVE-2009-0675, CVE-2009-0676, CVE-2009-1046 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: Please see the SUSE Security Summary Report. 6) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Problem Description and Brief Discussion The Linux kernel for SUSE Linux Enterprise 10 Service Pack 2 was updated to fixes various bugs and several security issues. Following security issues were fixed: CVE-2009-0675: The skfp_ioctl function in drivers/net/skfp/skfddi.c in the Linux kernel permits SKFP_CLR_STATS requests only when the CAP_NET_ADMIN capability is absent, instead of when this capability is present, which allows local users to reset the driver statistics, related to an "inverted logic" issue. CVE-2009-0676: The sock_getsockopt function in net/core/sock.c in the Linux kernel does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel memory via an SO_BSDCOMPAT getsockopt request. CVE-2009-0028: The clone system call in the Linux kernel allows local users to send arbitrary signals to a parent process from an unprivileged child process by launching an additional child process with the CLONE_PARENT flag, and then letting this new process exit. CVE-2008-1294: The Linux kernel does not check when a user attempts to set RLIMIT_CPU to 0 until after the change is made, which allows local users to bypass intended resource limits. CVE-2009-0065: Buffer overflow in net/sctp/sm_statefuns.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel allows remote attackers to have an unknown impact via an FWD-TSN (aka FORWARD-TSN) chunk with a large stream ID. CVE-2009-1046: The console selection feature in the Linux kernel when the UTF-8 console is used, allows physically proximate attackers to cause a denial of service (memory corruption) by selecting a small number of 3-byte UTF-8 characters, which triggers an an off-by-two memory error. It is is not clear if this can be exploited at all. Also a huge number of regular bugs were fixed, please see the RPM changelog for full details. 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 <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 http://download.novell.com/index.jsp?search=Search&keywords=1f9272102cdb11fea73949ffdb5ba881 SUSE Linux Enterprise 10 SP2 DEBUGINFO for IBM zSeries 64bit http://download.novell.com/index.jsp?search=Search&keywords=2167d7c3381356f1edd1695673f5b5e3 SUSE Linux Enterprise 10 SP2 DEBUGINFO for IBM POWER http://download.novell.com/index.jsp?search=Search&keywords=8c191558bacc4e54ae26ddcf21d10f9f SUSE Linux Enterprise 10 SP2 DEBUGINFO for IPF http://download.novell.com/index.jsp?search=Search&keywords=d70827089b862762d58e4a5f83a612df SUSE Linux Enterprise Server 10 SP2 http://download.novell.com/index.jsp?search=Search&keywords=1f9272102cdb11fea73949ffdb5ba881 http://download.novell.com/index.jsp?search=Search&keywords=2167d7c3381356f1edd1695673f5b5e3 http://download.novell.com/index.jsp?search=Search&keywords=8c191558bacc4e54ae26ddcf21d10f9f http://download.novell.com/index.jsp?search=Search&keywords=d70827089b862762d58e4a5f83a612df http://download.novell.com/index.jsp?search=Search&keywords=fa9be097c78c2f4acb003b27ea5b6cce SLE SDK 10 SP2 http://download.novell.com/index.jsp?search=Search&keywords=1f9272102cdb11fea73949ffdb5ba881 http://download.novell.com/index.jsp?search=Search&keywords=8c191558bacc4e54ae26ddcf21d10f9f http://download.novell.com/index.jsp?search=Search&keywords=d70827089b862762d58e4a5f83a612df http://download.novell.com/index.jsp?search=Search&keywords=fa9be097c78c2f4acb003b27ea5b6cce SUSE Linux Enterprise 10 SP2 DEBUGINFO http://download.novell.com/index.jsp?search=Search&keywords=1f9272102cdb11fea73949ffdb5ba881 http://download.novell.com/index.jsp?search=Search&keywords=8c191558bacc4e54ae26ddcf21d10f9f http://download.novell.com/index.jsp?search=Search&keywords=d70827089b862762d58e4a5f83a612df http://download.novell.com/index.jsp?search=Search&keywords=fa9be097c78c2f4acb003b27ea5b6cce SUSE Linux Enterprise Desktop 10 SP2 http://download.novell.com/index.jsp?search=Search&keywords=1f9272102cdb11fea73949ffdb5ba881 http://download.novell.com/index.jsp?search=Search&keywords=fa9be097c78c2f4acb003b27ea5b6cce SUSE Linux Enterprise Desktop 10 SP2 for x86 http://download.novell.com/index.jsp?search=Search&keywords=fa9be097c78c2f4acb003b27ea5b6cce ______________________________________________________________________________ 5) Pending Vulnerabilities, Solutions, and Work-Arounds: Please see the 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>.
