Description
ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 does not properly account for symbolic links in the IsRightsAuthorizedByName security policy check, allowing configured policy restrictions to be bypassed. Local attackers who can create a symlink can point it at a policy-restricted path to evade the configured policy.
