What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

ImageMagick before 7.1.2-33 contains a memory leak vulnerability in the MAT decoder that fails to release allocated memory in a specific error path. Attackers can supply crafted MAT files that trigger this error path repeatedly, causing small memory leaks that gradually consume process memory.
