Red Hat: RHSA-2014:1795-01 Moderate: cups-filters DoS and Access Issues

red hat
Calendar Grey November 3, 2014
Dist Redhat Esm H88
A minor refresh has been released for cups-filters that tackles a couple of vulnerabilities in the Red Hat Enterprise Linux 7 distribution.
Updated cups-filters packages that fix two security issues are now available for Red Hat Enterprise Linux 7

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 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.
