Updated gimp packages that fix three security issues are now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The GIMP is an image composition and editing program. A stack-based buffer overflow flaw, a heap-based buffer overflow, and an integer overflow flaw were found in the way GIMP loaded certain X Window System image dump files. A remote attacker could provide a specially crafted XWD image file that, when processed, would cause the XWD plug-in to crash or, potentially, execute arbitrary code with the privileges of the user running the GIMP. The CVE-2013-1913 and CVE-2013-1978 issues were discovered by Murray McAllister of the Red Hat Security Response Team. Users of the GIMP are advised to upgrade to these updated packages, which correct these issues. The GIMP must be restarted for the update to take effect.
