"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied
patch available.

  - When using `CURLOPT_PINNEDPUBLICKEY` option with libcurl or `--pinnedpubkey` with the curl tool,curl
    should check the public key of the server certificate to verify the peer. This check was skipped in a
    certain condition that would then make curl allow the connection without performing the proper check, thus
    not noticing a possible impostor. To skip this check, the connection had to be done with QUIC with ngtcp2
    built to use GnuTLS and the user had to explicitly disable the standard certificate verification.
    (CVE-2025-13034)

Note that Nessus relies on the presence of the package as reported by the vendor.");
