Description:
An integer overflow vulnerability was reported in libXpm. A remote user may be able to cause arbitrary code to be executed.
The 'lib/scan.c' code does not properly validate user-supplied data contained in image files. A remote user can create a specially crafted image file that, when processed by the target user or application, will trigger the overflow and execute arbitrary code.
Negative values in the 'image->bitmap_unit' variable can trigger the overflow.

Impact:
A remote user can create an image that, when processed by libXpm, will execute arbitrary code on the target system.
