"The remote Rocky Linux 9 host has packages installed that are affected by a vulnerability as referenced in the
RLSA-2023:0333 advisory.

  - When doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to
    ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle
    previously was used to issue a `PUT` request which used that callback. This flaw may surprise the
    application and cause it to misbehave and either send off the wrong data or use memory after free or
    similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is
    changed from a PUT to a POST. (CVE-2022-32221)

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