imlib2 -- XPM processing buffer overflow vulnerability

Secunia reports:

A vulnerability has been discovered in imlib2, which can
be exploited by malicious people to potentially compromise
an application using the library.
The vulnerability is caused due to a pointer arithmetic
error within the “load()” function provided by the XPM
loader. This can be exploited to cause a heap-based buffer
overflow via a specially crafted XPM file.
Successful exploitation may allow execution of arbitrary
code.
