ImageMagick before 6.9.13-55 and 7.x before 7.1.2-30 contains a security policy bypass in the MAT decoder, which does not enforce configured temporary file size limits when reading highly compressed data. Attackers can supply a crafted MAT image whose decompressed data is written to temporary files larger than the policy allows, consuming disk resources.
