Comment 1 Laura Pardo 2018-09-03 17:04:35 UTC 
Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1624958]
Comment 3 Riccardo Schirone 2018-09-18 13:47:52 UTC 
Upstream patch:
https://github.com/ImageMagick/ImageMagick/commit/2c75f301d9ac84f91071393b02d8c88c8341c91c
Comment 4 Riccardo Schirone 2018-09-18 13:50:59 UTC 
GetMagickProperty function in MagickCore/property.c only checks whether `image` or `image_info` are not NULL, but when later it uses the `image` pointer it doesn't check if it is actually accessible or not.
Comment 6 Riccardo Schirone 2018-09-18 13:55:33 UTC 
Statement:

This issue did not affect the versions of ImageMagick as shipped with Red Hat Enterprise Linux 5 as they did not include the vulnerable code.
Comment 8 Riccardo Schirone 2020-04-15 10:30:47 UTC 
Upstream patch ImageMagick6:
