"Updated cups-filters packages fix security vulnerabilities :

Florian Weimer discovered that cups-filters incorrectly handled memory
in the urftopdf filter. An attacker could possibly use this issue to
execute arbitrary code with the privileges of the lp user
(CVE-2013-6473).

Florian Weimer discovered that cups-filters incorrectly handled memory
in the pdftoopvp filter. An attacker could possibly use this issue to
execute arbitrary code with the privileges of the lp user
(CVE-2013-6474, CVE-2013-6475).

Florian Weimer discovered that cups-filters did not restrict driver
directories in in the pdftoopvp filter. An attacker could possibly use
this issue to execute arbitrary code with the privileges of the lp
user (CVE-2013-6476).

Sebastian Krahmer discovered it was possible to use malicious
broadcast packets to execute arbitrary commands on a server running
the cups-browsed daemon (CVE-2014-2707).

In cups-filters before 1.0.53, out-of-bounds accesses in the
process_browse_data function when reading the packet variable could
leading to a crash, thus resulting in a denial of service
(CVE-2014-4337).

In cups-filters before 1.0.53, if there was only a single BrowseAllow
line in cups-browsed.conf and its host specification was invalid, this
was interpreted as if no BrowseAllow line had been specified, which
resulted in it accepting browse packets from all hosts
(CVE-2014-4338).

The CVE-2014-2707 issue with malicious broadcast packets, which had
been fixed in Mageia Bug 13216 (MGASA-2014-0181), had not been
completely fixed by that update. A more complete fix was implemented
in cups-filters 1.0.53 (CVE-2014-4336).

Note that only systems that have enabled the affected feature by using
the CreateIPPPrinterQueues configuration directive in
/etc/cups/cups-browsed.conf were affected by the CVE-2014-2707 /
CVE-2014-4336 issue."

"Updated cups-filters packages that fix two security issues are now
available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

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."
