-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: xorg-x11 Announcement ID: SUSE-SA:2011:016 Date: Wed, 13 Apr 2011 12:00:00 +0000 Affected Products: openSUSE 11.2 openSUSE 11.3 openSUSE 11.4 SUSE SLES 9 Open Enterprise Server Novell Linux POS 9 SLE SDK 10 SP3 SUSE Linux Enterprise Desktop 10 SP3 SUSE Linux Enterprise Server 10 SP3 SUSE Linux Enterprise Desktop 11 SP1 SUSE Linux Enterprise Server 11 SP1 SUSE Linux Enterprise Desktop 10 SP4 SLE SDK 10 SP4 SUSE Linux Enterprise Server 10 SP4 Vulnerability Type: remote code execution CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C) SUSE Default Package: yes Cross-References: CVE-2011-0465 Content of This Advisory: 1) Security Vulnerability Resolved: xorg-x11/xrdb remote code execution Problem Description 2) Solution or Work-Around 3) Special Instructions and Notes 4) Package Location and Checksums 5) Pending Vulnerabilities, Solutions, and Work-Arounds: none 6) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Problem Description and Brief Discussion The xrdb helper program of the xorg-x11 package passes untrusted input such as hostnames retrieved via DHCP or client hostnames of XDMCP sessions to popen() without sanitization. Therefore, remote attackers could execute arbitrary commands as root by assigning specially crafted hostnames to X11 servers or to XDMCP clients. CVE-2011-0465 has been assigned to this issue. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes It is recommended to install the xorg-x11 packages in runlevel 3, without the X11 server running. 4) Package Location and Checksums The preferred method for installing security updates is to use the YaST "Online Update" module or the "zypper" commandline tool. The package and patch management stack will detect which updates are required and automatically perform 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 to apply the update, replacing with the filename of the downloaded RPM package. x86 Platform: openSUSE 11.4: http://download.opensuse.org/update/11.4/rpm/i586/xorg-x11-7.6-43.44.1.i586.... http://download.opensuse.org/update/11.4/rpm/i586/xorg-x11-xauth-7.6-43.44.1... openSUSE 11.3: http://download.opensuse.org/update/11.3/rpm/i586/xorg-x11-7.5-12.3.1.i586.r... http://download.opensuse.org/update/11.3/rpm/i586/xorg-x11-xauth-7.5-12.3.1.... openSUSE 11.2: http://download.opensuse.org/update/11.2/rpm/i586/xorg-x11-7.4-35.5.1.i586.r... http://download.opensuse.org/update/11.2/rpm/i586/xorg-x11-xauth-7.4-35.5.1.... x86-64 Platform: openSUSE 11.4: http://download.opensuse.org/update/11.4/rpm/x86_64/xorg-x11-7.6-43.44.1.x86... http://download.opensuse.org/update/11.4/rpm/x86_64/xorg-x11-xauth-7.6-43.44... openSUSE 11.3: http://download.opensuse.org/update/11.3/rpm/x86_64/xorg-x11-7.5-12.3.1.x86_... http://download.opensuse.org/update/11.3/rpm/x86_64/xorg-x11-xauth-7.5-12.3.... openSUSE 11.2: http://download.opensuse.org/update/11.2/rpm/x86_64/xorg-x11-7.4-35.5.1.x86_... http://download.opensuse.org/update/11.2/rpm/x86_64/xorg-x11-xauth-7.4-35.5....

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 " 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 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.
