An issue was discovered in Magick++ in ImageMagick 6.9.7. A specially crafted file creating a nested exception could lead to a memory leak (thus, a DoS).
The ReadVIFFImage function in coders/viff.c in ImageMagick before 7.0.1-0 allows remote attackers to cause a denial of service (application crash) or have other unspecified impact via a crafted file.
The ReadGROUP4Image function in coders/tiff.c in ImageMagick does not check the return value of the fwrite function, which allows remote attackers to cause a denial of service (application crash) via a crafted file.
