"The remote Debian 11 / 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5664
advisory.

  - Jetty is a Java based web server and servlet engine. An HTTP/2 SSL connection that is established and TCP
    congested will be leaked when it times out. An attacker can cause many connections to end up in this
    state, and the server may run out of file descriptors, eventually causing the server to stop accepting new
    connections from valid clients. The vulnerability is patched in 9.4.54, 10.0.20, 11.0.20, and 12.0.6.
    (CVE-2024-22201)

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