Moderate: gimp security update

Updated gimp packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

The GIMP (GNU Image Manipulation Program) is an image composition and
editing program.

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the GIMP's Microsoft Windows Bitmap (BMP) and Personal Computer
eXchange (PCX) image file plug-ins. An attacker could create a
specially-crafted BMP or PCX image file that, when opened, could cause the
relevant plug-in to crash or, potentially, execute arbitrary code with the
privileges of the user running the GIMP. (CVE-2009-1570, CVE-2011-1178)

A heap-based buffer overflow flaw was found in the GIMP's Paint Shop Pro
(PSP) image file plug-in. An attacker could create a specially-crafted PSP
image file that, when opened, could cause the PSP plug-in to crash or,
potentially, execute arbitrary code with the privileges of the user running
the GIMP. (CVE-2010-4543)

A stack-based buffer overflow flaw was found in the GIMP's Sphere Designer
image filter. An attacker could create a specially-crafted Sphere Designer
filter configuration file that, when opened, could cause the Sphere
Designer plug-in to crash or, potentially, execute arbitrary code with the
privileges of the user running the GIMP. (CVE-2010-4541)

Red Hat would like to thank Stefan Cornelius of Secunia Research for
responsibly reporting the CVE-2009-1570 flaw.

Users of the GIMP are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The GIMP must be
restarted for the update to take effect.

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
