The QuantumTransferMode function in coders/tiff.c in GraphicsMagick 1.3.25 and earlier allows remote attackers to cause a denial of service via a small samples per pixel value in a CMYKA TIFF file.The WPG format reader in GraphicsMagick 1.3.25 and earlier allows remote attackers to cause a denial of service via vectors related to a ReferenceBlob and a NULL pointer.Heap-based buffer overflow in the WPG format reader in GraphicsMagick 1.3.25 and earlier allows remote attackers to have unspecified impact via a colormap with a large number of entries. The MagickMalloc function in magick/memory.c in GraphicsMagick 1.3.25 allows remote attackers to have unspecified impact via a crafted image, which triggers a memory allocation failure and a "file truncation error for corrupt file." The ReadSCTImage function in coders/sct.c in GraphicsMagick 1.3.25 allows remote attackers to cause a denial of service via a crafted SCT header. The ReadPCXImage function in coders/pcx.c in GraphicsMagick 1.3.25 allows remote attackers to have unspecified impact via a crafted image, which triggers a memory allocation failure and a "file truncation error for corrupt file." The MagickRealloc function in memory.c in Graphicsmagick 1.3.25 allows remote attackers to cause a denial of service via large dimensions in a jpeg image. Integer underflow in the parse8BIM function in coders/meta.c in GraphicsMagick 1.3.25 and earlier allows remote attackers to cause a denial of service via a crafted 8BIM chunk, which triggers a heap-based buffer overflow
