"The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dsa-5330 advisory.

  - An insufficiently protected credentials vulnerability exists in curl 4.9 to and include curl 7.82.0 are
    affected that could allow an attacker to extract credentials when follows HTTP(S) redirects is used with
    authentication could leak credentials to other services that exist on different protocols or port numbers.
    (CVE-2022-27774)

  - 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)

  - No description is available for this CVE. (CVE-2022-43551) (CVE-2022-43552)

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