Affected versions of this package are vulnerable to Symlink Attack through the CopyDelegateFile path in the VIDEO/APNG delegate code. An attacker can write output to a disallowed path by supplying a delegate-driven image write that copies a generated file to a destination the policy should forbid. The vulnerable code in MagickCore/video.c copies delegate output to image->filename without checking whether that destination is authorized for write access. In a policy-restricted deployment, this lets an untrusted image operation place files outside the allowed output locations, causing unauthorized file writes on the host.
