-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Summary Report Announcement ID: SUSE-SR:2005:021 Date: Fri, 30 Sep 2005 14:00:00 +0000 Cross-References: CAN-2005-0941, CAN-2005-2558, CAN-2005-2794 CAN-2005-2796, CAN-2005-2876 Content of this advisory: 1) Solved Security Vulnerabilities: - storeBackup insecure /tmp usage and permissions - squid remote denial of service problems - mysql stack overflow in function handling - util-linux umount privilege escalation - OpenOffice_org version upgrade - mediawiki cross site scripting problems 2) Pending Vulnerabilities, Solutions, and Work-Arounds: None 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. - storeBackup insecure /tmp usage and permissions This update upgrades storeBackup to version 1.19 and fixes following security issues: - storeBackup used insecure /tmp filenames. - storeBackup used insecure (world readable) file permissions for the backup root. Only SUSE Linux retail products contain storeBackup and are affected. - squid remote denial of service problems The web proxy squid was updated to fix two remotely exploitable denial of service vulnerabilities. One can be triggered by aborting a request and the other one occurs in sslConnectTimeout while handling malformed requests. This is tracked by the Mitre CVE IDs CAN-2005-2794 and CAN-2005-2796. All SUSE Linux based products containing squid are affected. - mysql stack overflow in function handling This update fixes a stack-based buffer overflow in MySQL's init_syms function that can be exploited by authenticated users with the privilege to create user-defined functions. This is tracked by the Mitre CVE ID CAN-2005-2558. All SUSE Linux based products including mysql are affected. - util-linux umount privilege escalation The remount option of umount allowed local users to clear certain security relevant flags such as the nosuid flag. This is tracked by the Mitre CVE ID CAN-2005-2876. All SUSE Linux based products are affected by this problem. - OpenOffice_org version upgrade OpenOffice.org on SUSE Linux 9.3 was upgraded to 2.0 Beta Milestone m125. This includes a large number of bug fixes in all areas. This update also fixes a buffer overflow in the MS Word document reader. By creating a specially crafted Word document a remote attacker could exploit this bug to execute arbitrary code under the user id of the user viewing the document (CAN-2005-0941). Note that this version will save files in the new, final XML format that cannot be read by the original SUSE Linux 9.3 version. Files saved with the original 9.3 version can be read without problems. - Mediawiki cross site scripting problems More cross site scripting problems were found in MediaWiki. The problems fixed in the 1.4.9 release have been back ported and are included in this security update. Only SUSE Linux 9.3 contains MediaWiki. ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds None ______________________________________________________________________________ 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 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 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.
