-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Summary Report Announcement ID: SUSE-SR:2005:015 Date: Tue, 07 Jun 2005 12:00:00 +0000 Cross-References: CAN-2005-1260 CAN-2005-1391 CAN-2005-1261 Content of this advisory: 1) Solved Security Vulnerabilities: - bzip2 decompression bomb - pound crash by overflow - gaim buffer overflow 2) Pending Vulnerabilities, Solutions, and Work-Arounds: - postgresql - perl-Net-Server 3) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Solved Security Vulnerabilities To avoid flooding mailing lists with SUSE Security Announcements for minor issues, SUSE Security releases weekly summary reports for the low profile vulnerability fixes. The SUSE Security Summary Reports do not list md5 sums or download URLs like the SUSE Security Announcements that are released for more severe vulnerabilities. Fixed packages for the following incidents are already available on our FTP server and via the YaST Online Update. - bzip2 decompression bomb bzip2 could crash or run into an endless loop when decompressing certain specially crafted archives. This problem has been fixed. This issue is tracked by the Mitre CVE ID CAN-2005-1260 and affects all SUSE Linux based distributions. - pound A security problem in pound, a reverse proxying server, was fixed where clients with too long host names could trigger crashes by overflowing a buffer. This is tracked by the Mitre CVE ID CAN-2005-1391. This affects SUSE Linux 9.2 and 9.3. - gaim A buffer overflow in the URL handling code of gaim has been fixed. Remote attackers could exploit this bug to execute arbitrary code under the privileges of the user running gaim. The Mitre CVE ID CAN-2005-1261 has been assigned to this issue. This affects all SUSE Linux Box products, SUSE Linux Desktop 1 and Novell Linux Desktop 9. ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds - postgresql Two security errors in PostgreSQL may allow an unprivileged database user to crash the backend process or allow an unprivileged user to gain the privileges of a database superuser. To fix those problems please carefully read the instructions on http://www.postgresql.org/about/news.315 This is tracked by the Mitre CVE IDs CAN-2005-1409 and CAN-2005-1410 All SUSE LINUX based products except for SLES8 are affected. - perl-Net-Server We earlier reported a format string problem in the perl-Net-Server perl modules. Against earlier suspicions this cannot be used to execute code, but just to crash (denial of service) the respective service. This is tracked by the Mitre CVE ID CAN-2005-1127. ______________________________________________________________________________ 3) 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 containing 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 integrity of a package needs to be verified to ensure that it has not been tampered with. 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 file name 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 included at the end of this announcement. - 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. In particular, the clear text signature should show proof of the authenticity of the text.
