-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: openssl Announcement ID: SUSE-SA:2005:061 Date: Wed, 19 Oct 2005 12:00:00 +0000 Affected Products: SUSE LINUX 10.0 SuSE Linux 9.0 SUSE LINUX 9.1 SUSE LINUX 9.2 SUSE LINUX 9.3 SuSE Linux Desktop 1.0 SuSE Linux Enterprise Server 8 SUSE Linux Enterprise Server 9 UnitedLinux 1.0 Novell Linux Desktop 9 Open Enterprise Server Vulnerability Type: protocol downgrade attack Severity (1-10): 7 SUSE Default Package: yes Cross-References: CAN-2005-2969 Content of This Advisory: 1) Security Vulnerability Resolved: openssl protocol downgrading attack 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 openssl cryptographic libraries have been updated to fix a protocol downgrading attack which allows a man-in-the-middle attacker to force the usage of SSLv2. This happens due to the work-around code of SSL_OP_MSIE_SSLV2_RSA_PADDING which is included in SSL_OP_ALL (which is commonly used in applications). (CAN-2005-2969) Additionally this update adds the Geotrusts Equifax Root1 CA certificate to allow correct certification against Novell Inc. websites and services. The same CA is already included in Mozilla, KDE, and curl, which use separate certificate stores. 2) Solution or Work-Around Please install the updated packages. A work-around would be to disable SSL v2 support in the applications. 3) Special Instructions and Notes Restart all services using SSL communication. 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: SUSE LINUX 10.0:

The packages are offered for installation from the maintenance web: http://support.novell.com/cgi-bin/search/searchtid.cgi?psdb/5ac94511860f4bb7... http://portal.suse.com/psdb/5ac94511860f4bb76c8ce92f5791934b.html http://support.novell.com/cgi-bin/search/searchtid.cgi?psdb/66fe930899c74b0a... http://portal.suse.com/psdb/66fe930899c74b0ad097886cced1db5c.html ______________________________________________________________________________ 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 <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: suse-security@suse.com - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to <suse-security-subscribe@suse.com>. suse-security-announce@suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to <suse-security-announce-subscribe@suse.com>. For general information or the frequently asked questions (FAQ), send mail to <suse-security-info@suse.com> or <suse-security-faq@suse.com>. ===================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>. The <security@suse.de> public key is listed below. ===================================================================== ______________________________________________________________________________ The information in this advisory may be distributed or reproduced, provided that the advisory is not modified in any way.
