ImageMagick before 7.1.2-31 contains a policy bypass vulnerability in the UHDR encoder that fails to perform policy checks during buffer allocation for image pixels. Attackers can bypass resource policies by processing specially crafted UHDR images, potentially causing denial of service through excessive memory allocation.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the fc4d0a5b-d0c6-11f1-bae2-3497f65b111b advisory.

    The ImageMagick project published security advisories for               issues fixed in releases 7.1.2-26 through 7.1.2-34.  They include               heap buffer overflows, use-after-free, out-of-bounds reads,               integer overflows, division by zero, memory leaks and security               policy bypasses in various coders and in the command-line               interface.  A crafted image file can crash the process, disclose               memory contents or circumvent the configured security policy.

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

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