Red Hat 7 RHSA-2016:2601-02 Moderate: Fontconfig Code Execution Risk

red hat
Calendar Grey November 3, 2016
Scroller Redhat
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ======================================================
An update for fontconfig is now available for Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

Summary

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)
Red Hat would like to thank Tobias Stoeckmann for reporting this issue.
Additional Changes:
