Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1350462]

Comment 2 Stefan Cornelius 2016-08-18 06:06:29 EDT

Although we do have affected code snippets, I could not find an attack vector to exploit this prior to the following commit:
https://github.com/ImageMagick/ImageMagick/commit/e9438e2a82d35b6657e908ff38ec0303f432b655

Statement:

This issue did not affect the versions of ImageMagick as shipped with Red Hat Enterprise Linux 5, 6, and 7.
