Description Andrej Nemec 2016-10-26 08:44:14 UTC 
It was discovered that the upstream fix for this issue was not complete. There is still a memory allocation failure in memory.c

Comment 1 Andrej Nemec 2016-10-26 08:47:47 UTC 
Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1381145]
Comment 2 Huzaifa S. Sidhpurwala 2017-01-20 08:44:16 UTC 
Upstream patch:

https://github.com/ImageMagick/ImageMagick/commit/ab2c9d6a8dd6d71b161ec9cc57a588b116b52322

Analysis:

Basically lowers map_length from 32 (fix for CVE-2016-8862) to the new value 22. Even without the previous fix, this flaw affects ImageMagick shipped with Red Hat Enterprise Linux, hence marking as affected.
