Multiple integer overflows in libgdiplus 2.6.7, as used in Mono, allow attackers to execute arbitrary code via (1) a crafted TIFF file, related to the gdiploadtiffimage function in tiffcodec.c; (2) a crafted JPEG file, related to the gdiploadjpegimageinternal function in jpegcodec.c; or (3) a crafted BMP file, related to the gdipreadbmpimage function in bmpcodec.c, leading to heap-based buffer overflows.
