Description

The remote host is affected by the vulnerability described in GLSA-200806-03 (Imlib 2: User-assisted execution of arbitrary code)

Stefan Cornelius (Secunia Research) reported two boundary errors in     Imlib2:
One of them within the load() function in the     file src/modules/loaders/loader_pnm.c when processing the header of a     PNM image file, possibly leading to a stack-based buffer overflow.
The second one within the load() function in the file     src/modules/loader_xpm.c when processing an XPM image file, possibly     leading to a stack-based buffer overflow.

Impact :

A remote attacker could entice a user to open a specially crafted PNM     or XPM image, possibly resulting in the execution of arbitrary code     with the rights of the user running the application using Imlib 2.

Workaround :

There is no known workaround at this time.
