In ImageMagick 7.0.6-10, a NULL Pointer Dereference issue is present in the ReadCUTImage function in coders/cut.c that could allow an attacker to cause a Denial of Service (in the QueueAuthenticPixelCacheNexus function within the MagickCore/cache.c file) by submitting a malformed image file.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
