Comment 1 Sam Fowler 2018-04-05 01:12:32 UTC

Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1563891]

Comment 3 Riccardo Schirone 2018-05-18 13:23:39 UTC

Statement:

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