A remote attacker could provide a specially-crafted PPM image that when opened in gegl executable would lead to crash, or, potentially arbitrary code execution with the privileges of the user running the binary. This issue was found by Murray McAllister, Red Hat Security Response Team. We have assigned CVE-2012-4433 to this issue.
