"The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in
the USN-5855-1 advisory.

  - ImageMagick 7.1.0-49 is vulnerable to Denial of Service. When it parses a PNG image (e.g., for resize),
    the convert process could be left waiting for stdin input. (CVE-2022-44267)

  - ImageMagick 7.1.0-49 is vulnerable to Information Disclosure. When it parses a PNG image (e.g., for
    resize), the resulting image could have embedded the content of an arbitrary. file (if the magick binary
    has permissions to read it). (CVE-2022-44268)

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