Doc Text:
A flaw was found in ImageMagick. This vulnerability involves a memory leak within the VIFF encoder, a component responsible for handling image files. An attacker could exploit this by providing specially crafted VIFF images, which would trigger memory allocation failures. This action can exhaust available system memory, leading to a denial of service (DoS) where the system becomes unresponsive.
