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.
