FreeBSD : fontconfig -- insufficiently cache file validation (44989c29-67d1-11e6-8b1d-c86000169601)

high Nessus Plugin ID 93061

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Debian security team reports :

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.

Solution

Update the affected package.
