CVE-2018-7443

Status: ModifiedMedium (6.5)—

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).

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
