"The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3007 advisory.

  - A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage()
    in coders/svg.c. This issue is due to not checking the return value from libxml2's
    xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.
    (CVE-2021-3596)

  - ImageMagick 7.1.0-27 is vulnerable to Buffer Overflow. (CVE-2022-28463)

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