Description

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)
