-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Summary Report Announcement ID: SUSE-SR:2007:016 Date: Fri, 10 Aug 2007 16:00:00 +0000 Cross-References: CVE-2007-3387, CVE-2007-3798 Content of this advisory: 1) Solved Security Vulnerabilities: - orarun insecure group membership - xpdf code base buffer overflow - findutils-locate: core clean cron-job any file removal problem - tcpdump BGP packet handler overflow 2) Pending Vulnerabilities, Solutions, and Work-Arounds: - next kernel update 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. - orarun insecure group membership SUSE provides a "orarun" package that helps with setting up Oracle servers. This package creates on installation a "oracle" user. Up to now the user is in the group "disk" to allow setting up raw disk partitions. This however allows the oracle user later to escalate privileges if for instance a program or script in the Oracle suite running as "oracle" user is compromised. We recommend removing the "disk" group membership from the "oracle" user. You can do so by doing: usermod -g oinstall -G dba oracle We will not provide fixed packages at this time since these could break customer setups, but future service packs or products will leave out the disk group. We thank José M. Fandiño for reporting this problem. - xpdf code base buffer overflow A buffer overflow in the xpdf code contained in cups,poppler,kpdf and others could be exploited by attackers to potentially execute arbitrary code (CVE-2007-3387). Only XPDF 3 code derivatives were affected, XPDF 2 code deviates do not write into the memory. - findutils-locate: core clean cron job any file removal problem The cron job that deletes old core files could be tricked to delete arbitrary files. Old core files are deleted if DELETE_OLD_CORE=yes is set. That is not the case by default though. The findutils-locate package was updated to fix this issue on the affected products. SUSE Linux Enterprise Server 9, 10, and SUSE Linux 10.0 and 10.1 were affected. We thank Jan Minář for reporting this problem. - tcpdump BGP packet handler overflow tcpdump was updated to fix a buffer overflow that could be triggered when displaying BGP packets (CVE-2007-3798). All SUSE Linux based products were affected. ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds - next kernel update A SLE 10 kernel update will be released in the next weeks to catch up on post-Service Pack 1 fixes and current security fixes. A SUSE Linux 10.1 kernel update will be released with the same code base. ______________________________________________________________________________ 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 " 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 to verify the signature of the package, replacing 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: 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-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 . ===================================================================== SUSE's security contact is or .
