Synopsis
Moderate: cups security update
Type/Severity
Security Advisory: Moderate
Topic
Updated cups packages that fix one security issue are now available for
Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.
Description
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.
Solution
Before applying this update, make sure all previously-released errata
