Summary

ImageMagick before 7.1.2-33 contains a policy bypass in its UHDR decoder. Width and height limits are checked only after decoding, so an unauthenticated remote attacker can supply a crafted UHDR image with oversized dimensions that is fully decoded, causing excessive resource consumption (CWE-400).

Description from the CNA

ImageMagick before 7.1.2-33 contains a policy bypass vulnerability in the UHDR decoder that allows attackers to evade image width and height limits because extent checks occur after decoding. Attackers can supply crafted UHDR images with oversized dimensions that are fully decoded before policy limits are enforced, causing excessive resource consumption.
