Fontconfig is designed to locate fonts within the system and select
them according to requirements specified by applications.
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)
