-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: evolution,evolution-data-server Announcement ID: SUSE-SA:2007:042 Date: Thu, 05 Jul 2007 18:00:00 +0000 Affected Products: SUSE LINUX 10.0 SUSE LINUX 10.1 openSUSE 10.2 SuSE Linux Desktop 1.0 Novell Linux Desktop 9 SUSE Linux Enterprise Desktop 10 SP1 SUSE Linux Enterprise Server 10 SP1 Vulnerability Type: remote code execution Severity (1-10): 6 SUSE Default Package: yes Cross-References: CVE-2007-3257 Content of This Advisory: 1) Security Vulnerability Resolved: remote code execution by malicious IMAP server 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 malicious IMAP server could execute code within evolution by sending a malformed response to a SEQUENCE command. (CVE-2007-3257) This requires the user to connect to this malicious server (or a DNS entry of a good one replaced pointed to a malicious one) For older products the problematic code lives in the evolution package, for newer ones in the evolution-data-server package. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes Please close and restart all running instances of evolution after 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. x86 Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/i586/evolution-data-server-1.8.2-11.i586.rpm cf0ef3332a1005a598dc01b9b8721c3b ftp://ftp.suse.com/pub/suse/update/10.2/rpm/i586/evolution-data-server-devel-1.8.2-11.i586.rpm 53c2edfea054edf680d16b9a6ebe1d6a SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/evolution-data-server-1.6.0-43.58.i586.rpm ac3b9d062feda507bc46bb4537c35f01 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/evolution-data-server-devel-1.6.0-43.58.i586.rpm 999c30d78f4bcedb92cc9d13acd4cb04 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/evolution-data-server-1.4.0-5.6.i586.rpm f81fc01aac70dacaef72067cd20e1789 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/evolution-data-server-devel-1.4.0-5.6.i586.rpm 0c5019714dc38967250d546e4240324b Power PC Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/ppc/evolution-data-server-1.8.2-11.ppc.rpm bedd7b5ecb09dc7ebe13b4ba5a39746c ftp://ftp.suse.com/pub/suse/update/10.2/rpm/ppc/evolution-data-server-devel-1.8.2-11.ppc.rpm 435aca4e7fd2047c8f65de84b4a460ba SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/evolution-data-server-1.6.0-43.58.ppc.rpm d58d33df2443fefe6dede70c06c0151e ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/evolution-data-server-devel-1.6.0-43.58.ppc.rpm e2be822ff9c625b8d6c2571d6003104e SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/evolution-data-server-1.4.0-5.6.ppc.rpm 7be262a623a6035ddbe8e885aaee59fc ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/evolution-data-server-devel-1.4.0-5.6.ppc.rpm 55e98a69b4e8570548966506ee8b8890 x86-64 Platform: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/evolution-data-server-1.8.2-11.x86_64.rpm ddf44956dd38e64e8fd8f352da504a28 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/evolution-data-server-32bit-1.8.2-11.x86_64.rpm 9f1ee1154618701bb018afdc4df07207 ftp://ftp.suse.com/pub/suse/update/10.2/rpm/x86_64/evolution-data-server-devel-1.8.2-11.x86_64.rpm af6d90f21a8574f9ed4a6ac26edc1ba9 SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/evolution-data-server-1.6.0-43.58.x86_64.rpm f71072d3a1b4cdcae9ac1e4464088b20 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/evolution-data-server-32bit-1.6.0-43.58.x86_64.rpm e19ff9bd8b3a607dba310ce9f515fec5 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/evolution-data-server-devel-1.6.0-43.58.x86_64.rpm d080eb77092927c24cd6977f18011008 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/evolution-data-server-1.4.0-5.6.x86_64.rpm 8a82624a404f4a37aeabb10f663f39f9 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/evolution-data-server-32bit-1.4.0-5.6.x86_64.rpm 64b949a2a7feee1015b0172d9d8f4688 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/evolution-data-server-devel-1.4.0-5.6.x86_64.rpm 6d3f26332fd7aee190f9a801411a3ebd Sources: openSUSE 10.2: ftp://ftp.suse.com/pub/suse/update/10.2/rpm/src/evolution-data-server-1.8.2-11.src.rpm cb868a3ffb3dbd880f1eabf52b9a2b2f SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/src/evolution-data-server-1.6.0-43.58.src.rpm b20034e320b6dc7a78c00ac775bd798b SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/evolution-data-server-1.4.0-5.6.src.rpm e84e74ba25d843e82e15392d125a8c44 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>. opensuse-security-announce@opensuse.org - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to <opensuse-security-announce+subscribe@opensuse.org>. ===================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>.
