The WriteImages function in magick/constitute.c in ImageMagick before 6.9.2-4 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted image file.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
