Comment 1 Laura Pardo 2018-06-22 21:34:59 UTC 
Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1594421]
Comment 4 Riccardo Schirone 2018-08-02 11:03:07 UTC 
When writing a DIB file, ImageMagick incorrectly allocates the pixels array on the heap, using the wrong size. When converting a crafted image file to the DIB format, this flaw could be used to write beyond the limits, overwriting other data on the heap and causing a Denial of Service or other unspecified effects.
