Upstream patch
The WritePSImage() function fails to properly enforce the boundaries of a stack-based buffer when converting an image into a PostScript file. A malicious attacker could create a specially crafted image, which, when converted, could lead to a stack-based buffer overflow and, possibly, execution of arbitrary code. Successful exploitation requires that RLE compression is used.
