Comment 1 Laura Pardo 2018-09-03 13:04:35 EDT

Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1624958]

Comment 3 Riccardo Schirone 2018-09-18 09:47:52 EDT

Upstream patch:
https://github.com/ImageMagick/ImageMagick/commit/2c75f301d9ac84f91071393b02d8c88c8341c91c

Comment 4 Riccardo Schirone 2018-09-18 09:50:59 EDT

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 09:55:33 EDT

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.
