Official description
ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a null pointer dereference in the DJVU decoder because the result of a memory allocation is not checked before use. Attackers can supply a DJVU image that, when processed under conditions where the allocation fails, crashes the process and causes a denial of service.
