ReadXBMImage in coders/xbm.c in ImageMagick before 7.0.8-9 leaves data uninitialized when processing an XBM file that has a negative pixel value. If the affected code is used as a library loaded into a process that includes sensitive information, that information sometimes can be leaked via the image data.
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.
A heap-based buffer over-read in SampleImage() in MagickCore/resize.c in ImageMagick 7.0.6-8 Q16 allows remote attackers to cause a denial of service via a crafted file.
ImageMagick 7.0.6-8 Q16 mishandles EOF checks in ReadMPCImage in coders/mpc.c, leading to division by zero in GetPixelCacheTileSize in MagickCore/cache.c, allowing remote attackers to cause a denial of service via a crafted file.
A heap-based buffer overflow in WritePCXImage in coders/pcx.c in ImageMagick 7.0.6-8 Q16 allows remote attackers to cause a denial of service or code execution via a crafted file.
Null Pointer Dereference in the IdentifyImage function in MagickCore/identify.c in ImageMagick through 7.0.6-10 allows an attacker to perform denial of service by sending a crafted image file.
