"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3288 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)

  - libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed
    that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for
    subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were
    left out from the configuration match checks, making themmatch too easily. (CVE-2022-27782)

  - 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)

  - When curl is used to retrieve and parse cookies from a HTTP(S) server, itaccepts cookies using control
    codes that when later are sent back to a HTTPserver might make the server return 400 responses.
    Effectively allowing asister site to deny service to all siblings. (CVE-2022-35252)

  - 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.");
