news 28 Posted October 29, 2010 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: cups security update Advisory ID: RHSA-2010:0811-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0811.html Issue date: 2010-10-28 CVE Names: CVE-2010-2431 CVE-2010-2941 ===================================================================== 1. Summary: Updated cups packages that fix two security issues are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 3. Description: The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX operating systems. A use-after-free flaw was found in the way the CUPS server parsed Internet Printing Protocol (IPP) packets. A malicious user able to send IPP requests to the CUPS server could use this flaw to crash the CUPS server or, potentially, execute arbitrary code with the privileges of the CUPS server. (CVE-2010-2941) A possible privilege escalation flaw was found in CUPS. An unprivileged process running as the "lp" user (such as a compromised external filter program spawned by the CUPS server) could trick the CUPS server into overwriting arbitrary files as the root user. (CVE-2010-2431) Red Hat would like to thank Emmanuel Bouillon of NATO C3 Agency for reporting the CVE-2010-2941 issue. Users of cups are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the cupsd daemon will be restarted automatically. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5.
