Description
A flaw was found in ImageMagick, a software suite for editing and manipulating digital images. A remote attacker could exploit this vulnerability by providing a specially crafted image containing an invalid <map> element to the Magick Scripting Language (MSL) interpreter. This flaw causes a use-after-free, leading to an application crash and resulting in a Denial of Service (DoS).
Statement
MODERATE: This flaw in ImageMagick allows a use-after-free vulnerability when processing a specially crafted MSL <map> element. An attacker could provide a malicious image file, leading to a denial of service due to application crashes. This affects systems where ImageMagick is used to process untrusted image files.
