Red Hat Security Advisory: gegl security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:1455 Final 1 1 2012-11-12T18:19:00Z Current version 2012-11-12T18:19:00Z 2012-11-12T18:19:00Z Red Hat rhsa-to-cvrf 1.0.1484 2012-11-12T18:32:01Z 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.
