gegl security update

CentOS Errata and Security Advisory CESA-2012:1455

GEGL (Generic Graphics Library) is a graph-based image processing
framework.

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the way the gegl utility processed .ppm (Portable Pixel Map) image
files. An attacker could create a specially-crafted .ppm file that, when
opened in gegl, would cause gegl to crash or, potentially, execute
arbitrary code. (CVE-2012-4433)

This issue was discovered by Murray McAllister of the Red Hat Security
Response Team.

Users of gegl should upgrade to these updated packages, which contain a
backported patch to correct this issue.
