The following security problems have been fixed: CVE-2008-5079: net/atm/svc.c in the ATM subsystem allowed local users to cause a denial of service (kernel infinite loop) by making two calls to svc_listen for the same socket, and then reading a /proc/net/atm/ *vc file, related to corruption of the vcc table. CVE-2008-5029: The __scm_destroy function in net/core/scm.c makes indirect recursive calls to itself through calls to the fput function, which allows local users to cause a denial of service (panic) via vectors related to sending an SCM_RIGHTS message through a UNIX domain socket and closing file descriptors. CVE-2008-4933: Buffer overflow in the hfsplus_find_cat function in fs/hfsplus/catalog.c allowed attackers to cause a denial of service (memory corruption or system crash) via an hfsplus filesystem image with an invalid catalog namelength field, related to the hfsplus_cat_build_key_uni function. CVE-2008-5025: Stack-based buffer overflow in the hfs_cat_find_brec function in fs/hfs/catalog.c allowed attackers to cause a denial of service (memory corruption or system crash) via an hfs filesystem image with an invalid catalog namelength field, a related issue to CVE-2008-4933. CVE-2008-5182: The inotify functionality might allow local users to gain privileges via unknown vectors related to race conditions in inotify watch removal and umount. A lot of other bugs were fixed, a detailed list can be found in 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 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 -Fhvto apply the update, replacing 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 10 SP2 DEBUGINFO for IBM POWER https://download.novell.com/index.jsp?search=Search&keywords=315c54bd455583ce56f6bcbe19c768f9 SUSE Linux Enterprise 10 SP2 DEBUGINFO for IPF https://download.novell.com/index.jsp?search=Search&keywords=a91d4196357d841dd0ee16be55b3c171 SUSE Linux Enterprise 10 SP2 DEBUGINFO for IBM zSeries 64bit https://download.novell.com/index.jsp?search=Search&keywords=25b427c3c9c9b792a1e2c6f6c13f893d SUSE Linux Enterprise Desktop 10 SP2 for AMD64 and Intel EM64T https://download.novell.com/index.jsp?search=Search&keywords=a12607704b9e51847bb7b81ca6d58c3b SUSE Linux Enterprise Server 10 SP2 https://download.novell.com/index.jsp?search=Search&keywords=315c54bd455583ce56f6bcbe19c768f9 https://download.novell.com/index.jsp?search=Search&keywords=a91d4196357d841dd0ee16be55b3c171 https://download.novell.com/index.jsp?search=Search&keywords=25b427c3c9c9b792a1e2c6f6c13f893d https://download.novell.com/index.jsp?search=Search&keywords=a12607704b9e51847bb7b81ca6d58c3b https://download.novell.com/index.jsp?search=Search&keywords=14d206b16e1f6db4bc74003f9d937ed2 SLE SDK 10 SP2 https://download.novell.com/index.jsp?search=Search&keywords=315c54bd455583ce56f6bcbe19c768f9 https://download.novell.com/index.jsp?search=Search&keywords=a91d4196357d841dd0ee16be55b3c171 https://download.novell.com/index.jsp?search=Search&keywords=a12607704b9e51847bb7b81ca6d58c3b https://download.novell.com/index.jsp?search=Search&keywords=14d206b16e1f6db4bc74003f9d937ed2 SUSE Linux Enterprise 10 SP2 DEBUGINFO https://download.novell.com/index.jsp?search=Search&keywords=315c54bd455583ce56f6bcbe19c768f9 https://download.novell.com/index.jsp?search=Search&keywords=a91d4196357d841dd0ee16be55b3c171 https://download.novell.com/index.jsp?search=Search&keywords=a12607704b9e51847bb7b81ca6d58c3b https://download.novell.com/index.jsp?search=Search&keywords=14d206b16e1f6db4bc74003f9d937ed2 SUSE Linux Enterprise Desktop 10 SP2 https://download.novell.com/index.jsp?search=Search&keywords=a12607704b9e51847bb7b81ca6d58c3b https://download.novell.com/index.jsp?search=Search&keywords=14d206b16e1f6db4bc74003f9d937ed2 SUSE Linux Enterprise Desktop 10 SP2 for x86 https://download.novell.com/index.jsp?search=Search&keywords=14d206b16e1f6db4bc74003f9d937ed2 ______________________________________________________________________________ 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 replacing with the name of the file where you saved the announcement. The output for a valid signature looks like: gpg: Signature made using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team " where 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 to verify the signature of the package, replacing 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-announce@opensuse.org - SUSE's announce-only mailing list.
