CVE-2018-7443 is a vulnerability of currently unknown severity. 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).. EPSS estimates a 3.34% chance of exploitation in the next 30 days.
