Description
ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 incorrectly parses delegate invocations, which can allow an executable blocked in policy.xml to still run. An attacker who gets ImageMagick to process input that triggers a delegate invocation can bypass the administrator-defined policy and execute the blocked program.
