In the GetOpenCLCachedFilesDirectory function in magick/opencl.c in ImageMagick 7.0.7, a NULL pointer dereference vulnerability occurs because a memory allocation result is not checked, related to GetOpenCLCacheDirectory.
In ImageMagick 7.0.7, a NULL pointer dereference vulnerability was found in the function BenchmarkOpenCLDevices in MagickCore/opencl.c because a memory allocation result is not checked.
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.
In ImageMagick 7.0.7-16 Q16, a vulnerability was found in the function ReadOnePNGImage in coders/png.c, which allows attackers to cause a denial of service (ReadOneMNGImage large loop) via a crafted mng image file.
In ImageMagick 7.0.7-16 Q16 x86_64 2017-12-21, there is a heap-based buffer over-read in ReadOneMNGImage in coders/png.c, related to length calculation and caused by an off-by-one error.
In ImageMagick 7.0.7-16 Q16 x86_64 2017-12-21, there is a stack-based buffer over-read in WriteWEBPImage in coders/webp.c, related to a WEBP_DECODER_ABI_VERSION check.
In ImageMagick 7.0.7-16 Q16, a memory leak vulnerability was found in the function WriteOnePNGImage in coders/png.c, which allows attackers to cause a denial of service via a crafted PNG image file.
In ImageMagick 7.0.7-16 Q16, a memory leak vulnerability was found in the function GetImagePixelCache in magick/cache.c, which allows attackers to cause a denial of service via a crafted MNG image file that is processed by ReadOneMNGImage.
