Moderate: gegl security update
Security Advisory: Moderate
Updated gegl packages that fix one security issue are now available for
Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.
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.
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
