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 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the MSL decoder that fails to release allocated memory when processing a crafted MSL image. Attackers can supply crafted MSL files for processing to repeatedly leak memory, causing resource exhaustion and denial of service.
