-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: kernel Announcement ID: SUSE-SA:2010:023 Date: Thu, 06 May 2010 13:00:00 +0000 Affected Products: SLE SDK 10 SP2 SUSE Linux Enterprise Desktop 10 SP2 SUSE Linux Enterprise Server 10 SP2 Vulnerability Type: remote denial of service CVSS v2 Base Score: 7.8 (AV:N/AC:L/Au:N/C:N/I:N/A:C) SUSE Default Package: yes Cross-References: CVE-2009-4020, CVE-2009-4537, CVE-2010-0410 CVE-2010-1083, CVE-2010-1086, CVE-2010-1088 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 This update fixes several security issues and various bugs in the SUSE Linux Enterprise 10 SP 2 kernel. The bugs fixed include a serious data corruption regression in NFSv4 introduced by the previous update. Following security issues were fixed: CVE-2009-4537: drivers/net/r8169.c in the r8169 driver in the Linux kernel does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to (1) cause a denial of service (temporary network outage) via a packet with a crafted size, in conjunction with certain packets containing A characters and certain packets containing E characters; or (2) cause a denial of service (system crash) via a packet with a crafted size, in conjunction with certain packets containing '0' characters, related to the value of the status register and erroneous behavior associated with the RxMaxSize register. CVE-2010-1086: The ULE decapsulation functionality in drivers/media/dvb/dvb-core/dvb_net.c in dvb-core in the Linux kernel earlier allows attackers to cause a denial of service (infinite loop) via a crafted MPG2-TS frame, related to an invalid Payload Pointer ULE. CVE-2010-1088: fs/namei.c in Linux kernel does not always follow NFS automount "symlinks," which allows attackers to have an unknown impact, related to LOOKUP_FOLLOW. CVE-2009-4020: Stack-based buffer overflow in the hfs subsystem in the Linux kernel allows remote attackers to have an unspecified impact via a crafted Hierarchical File System (HFS) filesystem, related to the hfs_readdir function in fs/hfs/dir.c. CVE-2010-1083: The processcompl_compat function in drivers/usb/core/devio.c in the Linux kernel does not clear the transfer buffer before returning to user space when a USB command fails, which might make it easier for physically proximate attackers to obtain sensitive information (kernel memory). CVE-2010-0410: drivers/connector/connector.c in the Linux kernel allows local users to cause a denial of service (memory consumption and system crash) by sending the kernel many NETLINK_CONNECTOR messages. 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/patch/finder/?keywords=37bb490b2d9ca27c1027e09c04...

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>.
