In ImageMagick 7.0.7-16 Q16 x86_64 2017-12-22, an infinite loop vulnerability was found in the function ReadMIFFImage in coders/miff.c, which allows attackers to cause a denial of service (CPU exhaustion) via a crafted MIFF image file.
In ImageMagick 7.0.7-16 Q16 x86_64 2017-12-25, there is a use-after-free in ReadOneMNGImage in coders/png.c, which allows attackers to cause a denial of service via a crafted MNG image file that is mishandled in an MngInfoDiscardObject call.
In ImageMagick 7.0.7-16 Q16 x86_64 2017-12-22, an infinite loop vulnerability was found in the function ReadTXTImage in coders/txt.c, which allows attackers to cause a denial of service (CPU exhaustion) via a crafted image file that is mishandled in a GetImageIndexInList call.
In ImageMagick 7.0.7-23 Q16 x86_64 2018-01-24, there is a heap-based buffer over-read in ReadSUNImage in coders/sun.c, which allows attackers to cause a denial of service (application crash in SetGrayscaleImage in MagickCore/quantize.c) via a crafted SUN image file.
In ImageMagick 7.0.7-28, there is an infinite loop in the ReadOneMNGImage function of the coders/png.c file. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted mng file.
ImageMagick 7.0.7-26 Q16 has excessive iteration in the DecodeLabImage and EncodeLabImage functions (coders/tiff.c), which results in a hang (tens of minutes) with a tiny PoC file. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tiff file.
