Security Fix(es):

  * It was found that cache files were insufficiently validated in
fontconfig. A local attacker could create a specially crafted cache file to
trigger arbitrary free() calls, which in turn could lead to arbitrary code
execution. (CVE-2016-5384)

Red Hat would like to thank Tobias Stoeckmann for reporting this issue.
