Red Hat Security Advisory 2012-1455-01 - GEGL 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 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. This issue was discovered by Murray McAllister of the Red Hat Security Response Team.
