-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Summary Report Announcement ID: SUSE-SR:2007:021 Date: Fri, 19 Oct 2007 17:00:00 +0000 Cross-References: CVE-2006-1861, CVE-2006-3467, CVE-2007-4074 CVE-2007-4224, CVE-2007-4569, CVE-2007-4924 CVE-2007-4995, CVE-2007-5208 Content of this advisory: 1) Solved Security Vulnerabilities: - hplip command injection - kdelibs3, kdebase3 security update - NX security update for PCF handling - festival daemon command injection - opal denial of service problem - openssl DTLS problem 2) Pending Vulnerabilities, Solutions, and Work-Arounds: - None listed this week. 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. - hplip command injection The daemon 'hpssd' could be exploited by users to execute arbitrary commands as root. hpssd only runs on systems that have HP all-in-one devices configured. In the default configuration the problem is not remotely exploitable as hpssd only listens on local interfaces (CVE-2007-5208). This issue has been fixed for SUSE Linux 10.0-10.3, and SUSE Linux Enterprise Desktop 10. - kdelibs3, kdebase3 security update kdebase3 and kdelibs3 were updated on all affected SUSE Linux products to fix the following problems: - Users could log in as root without having to enter the password if auto login was enabled and if kdm was configured to require the root password to shutdown the system (CVE-2007-4569). - Javascript code could modify the URL in the address bar to make the currently displayed web site appear to come from a different site (CVE-2007-4224). - NX security update for PCF handling The XFree code contained in NX was prone to integer overflows (CVE-2006-1861) and insufficiently protected against specially crafted PCF files (CVE-2006-3467). NX has been updated on SUSE Linux 10.0-10.3, it is not contained on other distributions. - festival daemon command injection The festival daemon runs as root (if started). The default config doesn't have a password set. A local attacker could therefore connect to the daemon to have commands executed as root (CVE-2007-4074). festival has been updated on all affected products. - opal denial of service problem The opal library contained a bug in the SIP protocol handler that could be exploited by attackers to crash applications using opal (CVE-2007-4924). Opal has been updated on openSUSE 10.2, 10.3 and SUSE Linux Desktop 10. - openssl DTLS problem A buffer overflow in the DTLS implementation of openssl could be exploited by attackers to potentially execute arbitrary code (CVE-2007-4995). openssl has been updated on all distributions that contain DTLS support. It is questionable if the DTLS support even worked before or used by applications at all, so we were likely not affected. ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds None listed this week. ______________________________________________________________________________ 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: 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+subscribe@opensuse.org>. 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 <opensuse-security-announce+subscribe@opensuse.org>. ===================================================================== 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.
