Description David Walser 2016-08-08 21:57:44 CEST
Debian has issued an advisory today (August 8):
https://lists.debian.org/debian-security-announce/2016/msg00222.html

The DSA will hopefully be posted here:
https://www.debian.org/security/2016/dsa-3644

Patched packages uploaded for Mageia 5 and Cauldron.

Advisory:
========================

Updated fontconfig packages fix security vulnerability:

Tobias Stoeckmann discovered that cache files are insufficiently validated in
fontconfig, a generic font configuration library. An attacker can trigger
arbitrary free() calls, which in turn allows double free attacks and therefore
arbitrary code execution. In combination with setuid binaries using crafted
cache files, this could allow privilege escalation (CVE-2016-5384).
