The vulnerability is caused due to an error within the handling of Bitmap files (e.g. .BMP, .DIB, .RLE) and can be exploited to cause a stack-based buffer overflow via a specially crafted Bitmap file.
Successful exploitation allows execution of arbitrary code.
The vulnerability is reported in Adobe Photoshop CS2 and CS3. Other versions may also be affected.
Do not open untrusted Bitmap files.
