Summary: Updated cups packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - 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 CUPS handled references in its file descriptors-handling interface. A remote attacker could, in a specially-crafted way, query for the list of current print jobs for a specific printer, leading to a denial of service (cupsd crash). (CVE-2009-3553) Several cross-site scripting (XSS) flaws were found in the way the CUPS web server interface processed HTML form content. If a remote attacker could trick a local user who is logged into the CUPS web interface into visiting a specially-crafted HTML page, the attacker could retrieve and potentially modify confidential CUPS administration data. (CVE-2009-2820) Red Hat would like to thank Aaron Sigel of Apple Product Security for responsibly reporting the CVE-2009-2820 issue. Users of cups are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the update, the cupsd daemon will be restarted automatically. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via 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. Bugs fixed (http://bugzilla.redhat.com/): 529833 - CVE-2009-2820 cups: Several XSS flaws in forms processed by CUPS web interface 530111 - CVE-2009-3553 cups: Use-after-free (crash) due improper reference counting in abstract file descriptors handling interface 6.
