"The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the
RLSA-2022:1851 advisory.

  - A flaw was found in JSS, where it did not properly free up all memory. Over time, the wasted memory builds
    up in the server memory, saturating the server's RAM. This flaw allows an attacker to force the invocation
    of an out-of-memory process, causing a denial of service. (CVE-2021-4213)

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