From URL:

Description
===========
Heap-use-after-free vulnerability in jasper-2.0.8. The vulnerability exists in code responsible for re-encoding the decoded input image file to a JP2 image. The vulnerability is caused by not setting related pointers to be null after the pointers are freed (i.e. missing Setting-Pointer-Null operations after free). The vulnerability can further cause double-free.

This bug has been assigned to CVE-2016-9591
