In ImageMagick 7.0.8-43 Q16, there is a heap-based buffer over-read in the function WriteTIFFImage of coders/tiff.c, which allows an attacker to cause a denial of service or possibly information disclosure via a crafted image file.
In coders/bmp.c in ImageMagick before 7.0.8-16, an input file can result in an infinite loop and hang, with high CPU and memory consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file.
In ImageMagick 7.x before 7.0.8-42 and 6.x before 6.9.10-42, there is a use after free vulnerability in the UnmapBlob function that allows an attacker to cause a denial of service by sending a crafted file.
