-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: foomatic-filters Announcement ID: SUSE-SA:2006:026 Date: Tue, 30 May 2006 14:00:00 +0000 Affected Products: SUSE LINUX 10.1 SUSE LINUX 10.0 SUSE LINUX 9.3 Vulnerability Type: remote code execution Severity (1-10): 7 SUSE Default Package: yes Cross-References: CVE-2004-0801 Content of This Advisory: 1) Security Vulnerability Resolved: shell meta character injection in foomatic-filters 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 A bug in cupsomatic/foomatic-filters that allowed remote printer users to execute arbitrary commands with the UID of the printer daemon has been fixed (CVE-2004-0801). While the same problem was fixed in earlier products, the fix got lost during package upgrade of foomatic-filters for SUSE Linux 9.3. Only SUSE Linux 9.3, 10.0 and 10.1 still contained this bug. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes None. 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 to apply the update, replacing with the filename of the downloaded RPM package. x86 Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/foomatic-filters-3.0.2-20.3.i586.rpm 4d21b1d07aa0924e0b0a8e0f5e27585d SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/foomatic-filters-3.0.2-4.2.i586.rpm 51aa413c3b1b2849d481548dac9fa7ee SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/foomatic-filters-3.0.2-3.2.i586.rpm 4998b7323800fd653046fa8fec46dd34 Power PC Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/foomatic-filters-3.0.2-20.3.ppc.rpm 5e496f8fe2c5f8c0aee67631b20a3f40 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/foomatic-filters-3.0.2-4.2.ppc.rpm de7e91b9376956f21c315bbbd10e979c x86-64 Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/foomatic-filters-3.0.2-20.3.x86_64.rpm 3ee1d1d97fb3618623847cac9c11e79a SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/foomatic-filters-3.0.2-4.2.x86_64.rpm e8351e415eb1700582810c553710aab9 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/foomatic-filters-3.0.2-3.2.x86_64.rpm 63214340cf7b1496ce288791335683d5 Sources: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/src/foomatic-filters-3.0.2-20.3.src.rpm a74521a9f8142f820f4cbdf941e1c1e1 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/foomatic-filters-3.0.2-4.2.src.rpm 4ba4114b528f3cd09a55485bc6d05402 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/foomatic-filters-3.0.2-3.2.src.rpm eb1518b6c768b5297e27ad282810be82 Our maintenance customers are notified individually. The packages are offered for installation from the maintenance web: ______________________________________________________________________________ 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 <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. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or RPM package: 1) Using the internal gpg signatures of the rpm package 2) MD5 checksums as provided in this announcement 1) 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. 2) If you need an alternative means of verification, use the md5sum command to verify the authenticity of the packages. Execute the command md5sum after you downloaded the file from a SUSE FTP server or its mirrors. Then compare the resulting md5sum with the one that is listed in the SUSE security announcement. Because the announcement containing the checksums is cryptographically signed (by security@suse.de), the checksums show proof of the authenticity of the package if the signature of the announcement is valid. Note that the md5 sums published in the SUSE Security Announcements are valid for the respective packages only. Newer versions of these packages cannot be verified. - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - General Linux and SUSE security discussion.
