Following security issues were fixed: CVE-2009-3547: A race condition during pipe open could be used by local attackers to elevate privileges. CVE-2009-2910: On x86_64 systems an information leak of high register contents (upper 32bit) was fixed. CVE-2009-3238: The randomness of the ASLR methods used in the kernel was increased. CVE-2009-1192: A information leak from the kernel due to uninitialized memory in AGP handling was fixed. CVE-2009-2909: A signed comparison in the ax25 sockopt handler was fixed which could be used to crash the kernel or potentially execute code. CVE-2009-2848: The execve function in the Linux kernel did not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit. CVE-2009-3002: Fixed various socket handler getname leaks, which could disclose memory previously used by the kernel or other userland processes to the local attacker. CVE-2009-1633: Multiple buffer overflows in the cifs subsystem in the Linux kernel allow remote CIFS servers to cause a denial of service (memory corruption) and possibly have unspecified other impact via (1) a malformed Unicode string, related to Unicode string area alignment in fs/cifs/sess.c; or (2) long Unicode characters, related to fs/cifs/cifssmb.c and the cifs_readdir function in fs/cifs/readdir.c. Also see the RPM changelog for more changes. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes 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&set_restricted=true&keywords=d151951fc3a1ac532d4cf09cdcf83600 SUSE Linux Enterprise 10 SP2 DEBUGINFO for IBM zSeries 64bit http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=3e34cd48fd5034abf8d9950ba6096357 SUSE Linux Enterprise 10 SP2 DEBUGINFO for IBM POWER http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=b1d2dae366b809eaadae10c9e6f31ea1 SUSE Linux Enterprise Desktop 10 SP2 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=d151951fc3a1ac532d4cf09cdcf83600 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=bf7b53d62cb6acefb16bcc6d4d6f5a8d SUSE Linux Enterprise Desktop 10 SP2 for x86 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=bf7b53d62cb6acefb16bcc6d4d6f5a8d SUSE Linux Enterprise Server 10 SP2 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=d151951fc3a1ac532d4cf09cdcf83600 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=3e34cd48fd5034abf8d9950ba6096357 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=b1d2dae366b809eaadae10c9e6f31ea1 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=bf7b53d62cb6acefb16bcc6d4d6f5a8d http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=2d7fb81cd7eea9be510d7a1a24ac77c1 SLE SDK 10 SP2 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=d151951fc3a1ac532d4cf09cdcf83600 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=b1d2dae366b809eaadae10c9e6f31ea1 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=bf7b53d62cb6acefb16bcc6d4d6f5a8d http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=2d7fb81cd7eea9be510d7a1a24ac77c1 SUSE Linux Enterprise 10 SP2 DEBUGINFO http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=d151951fc3a1ac532d4cf09cdcf83600 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=b1d2dae366b809eaadae10c9e6f31ea1 http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=bf7b53d62cb6acefb16bcc6d4d6f5a8d http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=2d7fb81cd7eea9be510d7a1a24ac77c1 SUSE Linux Enterprise 10 SP2 DEBUGINFO for IPF http://download.novell.com/index.jsp?search=Search&set_restricted=true&keywords=2d7fb81cd7eea9be510d7a1a24ac77c1 ______________________________________________________________________________ 5) Pending Vulnerabilities, Solutions, and Work-Arounds: - Pending kernels for CVE-2009-3547 problem SUSE Linux Enterprise 10 SP3 kernels will be released tomorrow. SUSE Linux Enterprise 9 kernels had another QA failure and so will be released approximately begin of next week. openSUSE 11.0, 11.1 and SUSE Linux Enterprise 11 kernels have "mmap_min_addr" protection by default and will be released in their regular release cycles. (Probably around end of November). ______________________________________________________________________________ 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.
