===================================================================== CERT-Renater Note d'Information No. 2005/VULN409 _____________________________________________________________________ DATE : 24/06/2005 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Systems running razor-agents. ====================================================================== ______________________________________________________________________________ SUSE Security Announcement Package: razor-agents Announcement ID: SUSE-SA:2005:035 Date: Tue, 23 Jun 2005 09:00:00 +0000 Affected Products: 8.2, 9.0, 9.1, 9.2, 9.3 Vulnerability Type: remote denial of service Severity (1-10): 4 SUSE Default Package: no Cross-References: None. Content of This Advisory: 1) Security Vulnerability Resolved: denial of service attack against Vipuls razor 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 Several bugs were fixed in Vipuls Razor spam detection framework. These bugs could lead to remote denial-of-service conditions due to processing malformed messages and possible stepping into infinite loops. 2) Solution or Work-Around Please install the updated packages. 3) Special Instructions and Notes Please restart any service using razor-agents. 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. Our maintenance customers are notified individually. The packages are offered for installation from the maintenance web. x86 Platform: SUSE Linux 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/razor-agents-2.67-3.2.i586.rpm 676b7c6d977f0ed2b92ba313fa269689 SUSE Linux 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/razor-agents-2.61-3.2.i586.rpm fc88751db9c4a14e5fbf6221d4ec5ad9 SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/i586/razor-agents-2.36-59.4.i586.rpm 889f8c37bbc80d520d6c4ecbfeff1913 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.1/rpm/src/razor-agents-2.36-59.4.src.rpm a49208f7438160852e1dff387a70beea SUSE Linux 9.0: ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/i586/razor-agents-2.34-54.i586.rpm 7d831ac330b9ca512722ac1754ec3236 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.0/rpm/src/razor-agents-2.34-54.src.rpm db088de6b5cb8a5b67dfa485fdd22991 SUSE Linux 8.2: ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/i586/razor-agents-2.126-122.i586.rpm d96fc57ad82f716dd421f0bca1c45b57 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/8.2/rpm/src/razor-agents-2.126-122.src.rpm 982a7860c698f1ea9a554128ce34b45b x86-64 Platform: SUSE Linux 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/razor-agents-2.67-3.2.x86_64.rpm a1cd46cabd6e45c8f9d5ad7405085d04 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/razor-agents-2.67-3.2.src.rpm 5f9642b047be597bfbed8229d3098e76 SUSE Linux 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/razor-agents-2.61-3.2.x86_64.rpm 18157e6d2a2582b9a45b3a62be18ddb5 source rpm(s): ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/src/razor-agents-2.61-3.2.src.rpm 7f9d70373765389ab8284bd274af6d2d SUSE Linux 9.1: ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/x86_64/razor-agents-2.36-59.4.x86_64.rpm a4824f88fcb85f610ca738b6c729744c source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.1/rpm/src/razor-agents-2.36-59.4.src.rpm 5b064357f7db0574e7b89add57a3738f SUSE Linux 9.0: ftp://ftp.suse.com/pub/suse/x86_64/update/9.0/rpm/x86_64/razor-agents-2.34-54.x86_64.rpm 6ecca2f0cd15f7804d04dac04ad22ce6 source rpm(s): ftp://ftp.suse.com/pub/suse/x86_64/update/9.0/rpm/src/razor-agents-2.34-54.src.rpm 7765df46f6b332e835da33ab04784d6e ______________________________________________________________________________ 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. 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.
