A flaw was found in ImageMagick. This vulnerability allows an attacker to cause a Denial of Service (DoS) by submitting a specially crafted image file for processing. When the Digital Negative (DNG) decoder is disabled, processing the file triggers a stack overflow in the TIFF decoder, leading to an application crash.
