In ImageMagick 7.0.7, a NULL pointer dereference vulnerability was found in the function saveBinaryCLProgram in magick/opencl.c because a program-lookup result is not checked, related to CacheOpenCLKernel.
In the ReadDCMImage function in coders/dcm.c in ImageMagick before 7.0.7-23, each redmap, greenmap, and bluemap variable can be overwritten by a new pointer. The previous pointer is lost, which leads to a memory leak. This allows remote attackers to cause a denial of service.
