What is CVE-2026-116147?

ImageMagick, a widely used image processing tool, is susceptible to a null pointer dereference vulnerability in its DJVU decoder. This issue arises due to the lack of proper memory allocation checks, allowing attackers to exploit the vulnerability by providing specially crafted DJVU images. When the decoder encounters a memory allocation failure, it can lead to a crash of the processing service, resulting in a denial of service. Users of affected versions should be vigilant and apply the necessary updates to mitigate potential risks.

Affected Version(s)

ImageMagick 7.0.0-0 < 7.1.2-33

ImageMagick 0 < 6.9.13-58
