3. Description:

The cups-filters package contains backends, filters, and other software
that was once part of the core CUPS distribution but is now maintained
independently.

An out-of-bounds read flaw was found in the way the process_browse_data()
function of cups-browsed handled certain browse packets. A remote attacker
could send a specially crafted browse packet that, when processed by
cups-browsed, would crash the cups-browsed daemon. (CVE-2014-4337)

A flaw was found in the way the cups-browsed daemon interpreted the
“BrowseAllow” directive in the cups-browsed.conf file. An attacker able to
add a malformed “BrowseAllow” directive to the cups-browsed.conf file could
use this flaw to bypass intended access restrictions. (CVE-2014-4338)

All cups-filters users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. After installing
this update, the cups-browsed 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
