DESCRIPTION:
Francis Provencher has discovered a vulnerability in libfpx, which
potentially can be exploited by malicious people to compromise an
application using the library.

The vulnerability is caused due to the "Free_All_Memory()" function
(jpeg/dectile.c) not properly setting certain decoder elements to
NULL after freeing them, which can be exploited to cause a
double-free condition via specially crafted FPX images.

The vulnerability is confirmed in version 1.3.1. Prior versions may
also be affected.

SOLUTION:
Update to version 1.3.1-1.

PROVIDED AND/OR DISCOVERED BY:
Francis Provencher, Protek Research Lab's via Secunia.
