Background

Affected packages

Description
===========

An integer overflow flaw was discovered that leads to an out-of-bounds
read and write in gs_ttf.ps.

Impact

possibly resulting in the execution of arbitrary code with the
privileges of the process or a Denial of Service condition.

Workaround
