-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Summary Report Announcement ID: SUSE-SR:2005:016 Date: Fri, 17 Jun 2005 14:00:00 +0000 Cross-References: CAN-2005-0160 CAN-2005-0161 CAN-2005-0961 Content of this advisory: 1) Solved Security Vulnerabilities: - gpg2 broken S/MIME signing - telnet environment option disclosure - unace buffer overflows - horde cross site scripting 2) Pending Vulnerabilities, Solutions, and Work-Arounds: - postgresql various fixes - gaim denial of service attack - perl-Net-Server denial of service attack - Sun Java applet privilege problems 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. - gpg2 The S/MIME signing using gpg2 was broken in SUSE Linux 9.3. Updated packages were released to fix this problem. - telnet The telnet client protocol can be abused by a malicious server to read the environment of the client site. This information in turn can be used as preparation for further attacks. This bug was reported by iDEFENSE [IDEF0865] and is tracked by the Mitre CVE ID Note that this patch changes the behavior of the telnet client regarding the rule of exported environment variables. Please consult the man page for further details. All SUSE Linux products are affected. - unace The unpacker "unace" had several buffer overflows while extracting, testing, or listing an archive file (CAN-2005-0160) as well as a buffer overflow while handling long command-line options (CAN-2005-0161). This affects all SUSE Linux versions including unace (8.2 up to 9.3). - horde cross site scripting A cross site scripting problem was fixed in horde application framework. This issue is tracked by the Mitre CVE ID CAN-2005-0961. All SUSE Linux 9.2 and SUSE Linux Enterprise Server 9 were affected. ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds - postgresql Two security problems 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. - gaim Several new denial of service problems were found in the gaim Instant Messenger, affecting all SUSE Linux based distributions including gaim. Updates are being prepared. - 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. - java applet privilege problems A critical flaw was found in the Sun Java run time environment which allows untrusted applets or JLNP (webstartable) files to circumvent access restrictions and read/write files on the system and start applications. We are currently preparing updates for this problem. All SUSE Linux products containing Sun Java are affected. ______________________________________________________________________________ 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.
