Description Laura Pardo 2018-02-27 15:40:17 UTC 
A flaw was found in ImageMagick. The ReadTIFFImage function in coders/tiff.c in ImageMagick 7.0.7-23 Q16 does not properly validate the amount of image data in a file, which allows remote attackers to cause a denial of service (memory allocation failure in the AcquireMagickMemory function in MagickCore/memory.c).
