"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2022:7643 advisory.

  - BIND 9.11.0 -> 9.11.36 9.12.0 -> 9.16.26 9.17.0 -> 9.18.0 BIND Supported Preview Editions: 9.11.4-S1 ->
    9.11.36-S1 9.16.8-S1 -> 9.16.26-S1 Versions of BIND 9 earlier than those shown - back to 9.1.0, including
    Supported Preview Editions - are also believed to be affected but have not been tested as they are EOL.
    The cache could become poisoned with incorrect records leading to queries being made to the wrong servers,
    which might also result in false information being returned to clients. (CVE-2021-25220)

  - BIND 9.16.11 -> 9.16.26, 9.17.0 -> 9.18.0 and versions 9.16.11-S1 -> 9.16.26-S1 of the BIND Supported
    Preview Edition. Specifically crafted TCP streams can cause connections to BIND to remain in CLOSE_WAIT
    status for an indefinite period of time, even after the client has terminated the connection.
    (CVE-2022-0396)

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