A heap-based buffer overflow flaw, leading to invalid free, was found in the way KISS CEL file format plug-in of Gimp, the GNU Image Manipulation Program, performed loading of certain palette files. A remote attacker could provide a specially-crafted KISS palette file that, when opened in Gimp would cause the CEL plug-in to crash or, potentially, execute arbitrary code with the privileges of the user running the gimp executable.

A heap-based buffer overflow flaw was found in the way Adobe Photoshop(tm) PSD plug-in of Gimp, the GNU Image Manipulation Program, performed decoding of headers, when loading certain Adobe Photoshop image files. A remote attacker could provide a specially-crafted PSD image file that, when opened in Gimp would lead to PSD plug-in crash or, potentially, arbitrary code execution with the privileges of the user running gimp executable.

The (1) psp (aka .tub), (2) bmp, (3) pcx, and (4) psd plugins in gimp allow user-assisted remote attackers to cause a denial of service (crash or memory consumption) via crafted image files, as discovered using the fusil fuzzing tool.
