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.
The vulnerability is confirmed in version 1.4.2. Other versions may also be affected.
Solution: Do not process untrusted XPM files.
Provided and/or discovered by: Reported by Julien Danjou in a Debian bug report.
