-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: clamav Announcement ID: SUSE-SA:2007:033 Date: Wed, 06 Jun 2007 15:00:00 +0000 Affected Products: SUSE LINUX 10.0 SUSE LINUX 10.1 openSUSE 10.2 SUSE SLES 9 Open Enterprise Server Novell Linux POS 9 Vulnerability Type: remote denial of service Severity (1-10): 6 SUSE Default Package: no Cross-References: CVE-2007-2650, CVE-2007-3023, CVE-2007-3024 Content of This Advisory: 1) Security Vulnerability Resolved: clamav security update 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 The anti-virus scan engine ClamAV was upgraded to version 0.90.3 to fix several security bugs: - Wrong calculation of buffer-end (CVE-2007-3023) - Use strict permissions for temporary files (CVE-2007-3024) - Heap corruption causing denial-of-service with corrupted rar archive (no CVE assigned at this time) - Detect block list loop in OLE2 scanner (CVE-2007-2650) Updated clamav packages for SUSE Linux Enterprise 10 will be released after Service Pack 1 is released. 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 <file.rpm> to apply the update, replacing <file.rpm> with the filename of the downloaded RPM package. x86 Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/i586/clamav-0.90.3-2.1.i586.rpm a8a37e2d3ccd914f91597f8f48cca99f ftp://ftp.suse.com/pub/suse/update/10.2/rpm/i586/clamav-db-0.90.3-2.1.i586.rpm fc9519bd40748e2d30037596375b5cca SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/clamav-0.90.3-3.1.i586.rpm 31d196d6eaf5c0c8f29dc4c21e4ff78d SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/clamav-0.90.3-2.1.i586.rpm 02e6bdaef4c68c484179275b0bee985f ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/clamav-db-0.90.3-2.1.i586.rpm 3191c5e50ffa62bdf817b65368786c8b Power PC Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/ppc/clamav-0.90.3-2.1.ppc.rpm 583fdbffc1e5069973eacc34c4de2947 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/ppc/clamav-db-0.90.3-2.1.ppc.rpm 29c2788eb45087ee974fad983f1b4964 SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/clamav-0.90.3-3.1.ppc.rpm 320d1bcc7a5e6718b95c368f7b1d4d7d SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/clamav-0.90.3-2.1.ppc.rpm 2b43aa34e2d3c302da79759f242cf91e ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/clamav-db-0.90.3-2.1.ppc.rpm ec1ae4d5d638bd223cf33e551bb382a7 x86-64 Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/clamav-0.90.3-2.1.x86_64.rpm 5a4b81479f025c99e304794b0c5b0c27 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/clamav-db-0.90.3-2.1.x86_64.rpm a81e693c4c371f6af4f98cfad4d615b5 SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/clamav-0.90.3-3.1.x86_64.rpm a42e875ca5f71ec7d7efab625d13b9e5 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/clamav-0.90.3-2.1.x86_64.rpm a75c1378b9a05f54a699996345e9b174 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/clamav-db-0.90.3-2.1.x86_64.rpm 702683c41d6ab2dd17acd3fcb2f2d163 Sources: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/src/clamav-0.90.3-2.1.src.rpm 3a018d00982f611bc847fcdbf3be0545 SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/src/clamav-0.90.3-3.1.src.rpm 2be2b9659f5bb2fe11e32fb98a409d37 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/clamav-0.90.3-2.1.src.rpm 2bd465210eed5eaa70fe16c1a64fed75 Our maintenance customers are notified individually.

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. 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 <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. 2) If you need an alternative means of verification, use the md5sum command to verify the authenticity of the packages. Execute the command md5sum <filename.rpm> 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: 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>. suse-security-announce@suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list.
