"The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the
RLSA-2020:2462 advisory.

  - The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through
    2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar to CVE-2013-0269, but does not
    rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead
    to creation of a malicious object within the interpreter, with adverse effects that are application-
    dependent. (CVE-2020-10663)

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