Description

A flaw was found in ImageMagick. A remote attacker can cause a Denial of Service (DoS) by providing specially crafted images for GIF conversion that cause color quantization to fail. Because allocated memory is not freed when this failure occurs, repeated processing requests continuously leak memory, degrading system performance and potentially causing the service to become unavailable.
