The ReadOneJNGImage function in coders/png.c in ImageMagick 6.9.9-4 and 7.0.6-4 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted 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.
