Red Hat Enterprise Linux: RHSA-2013:0580-01 Moderate: Cups Config Risk

red hat
Calendar Grey February 28, 2013
Dist Redhat Esm H88
New coffee-related software updates released, addressing critical risks in Red Hat Enterprise Linux platforms, essential for system administrators.
Updated cups packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6

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 https://access.redhat.com/articles/11258

Summary

The Common UNIX Printing System (CUPS) provides a portable printing layer for Linux, UNIX, and similar operating systems.
It was discovered that CUPS administrative users (members of the SystemGroups groups) who are permitted to perform CUPS configuration changes via the CUPS web interface could manipulate the CUPS configuration to gain unintended privileges. Such users could read or write arbitrary files with the privileges of the CUPS daemon, possibly allowing them to run arbitrary code with root privileges. (CVE-2012-5519)
After installing this update, the ability to change certain CUPS configuration directives remotely will be disabled by default. The newly introduced ConfigurationChangeRestriction directive can be used to enable the changing of the restricted directives remotely. Refer to Red Hat Bugzilla bug 875898 for more details and the list of restricted directives.
All users of cups are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing this update, the cupsd daemon will be restarted automatically.
