ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the JNG encoder when a blob cannot be opened. Attackers can trigger the memory leak by providing malformed JNG files that fail blob operations, causing resource exhaustion.

The remote host has a version of ImageMagick installed that is prior to 6.9.13-55, or 7.x prior to 7.1.2-26. It is, therefore, affected by a vulnerability.

    Multiple security vulnerabilities were discovered in imagemagick, a     software suite used for editing and manipulating digital images, which     could lead to denial of service, information disclosure or potentially     arbitrary code execution if malformed images are processed.

    For Debian 11 bullseye, these problems have been fixed in version     8:6.9.11.60+dfsg-1.3+deb11u16.

    For Debian 12 bookworm, these problems have been fixed in version     8:6.9.11.60+dfsg-1.6+deb12u13.

    We recommend that you upgrade your imagemagick packages.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the JNG encoder when a blob cannot be     opened. Attackers can trigger the memory leak by providing malformed JNG files that fail blob operations,     causing resource exhaustion. (CVE-2026-61866)

Note that Nessus relies on the presence of the package as reported by the vendor.
