Doc Text:
A flaw was found in ImageMagick. The `-concatenate` operation, used for combining images, lacks proper security policy checks. This oversight could allow an attacker to read from or write to file paths that should otherwise be restricted by the security policy. This could lead to unauthorized access to sensitive system resources.
