RHEL 5 : cups (RHSA-2009:1595)

medium Nessus Plugin ID 42850


The remote Red Hat host is missing one or more security updates.


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.

[Updated 12th January 2010] The packages list in this erratum has been updated to include missing i386 packages for Red Hat Enterprise Linux Desktop and RHEL Desktop Workstation.

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).

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.
