Description
ImageMagick before 6.9.13-56 and 7.x before 7.1.2-31 allows a security policy bypass when a policy uses coder, rather than module, as its domain. An attacker can supply a crafted image to evade coder-based policy restrictions, causing ImageMagick to process formats the administrator intended to block.
