Comment 1 Laura Pardo 2018-06-22 21:34:41 UTC 
Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1594420]
Comment 3 Riccardo Schirone 2018-08-02 08:16:35 UTC 
When writing a BMP file, ImageMagick incorrectly allocates the pixel_info array on the heap, using the wrong size. When converting a crafted image file to the BMP 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.
