"The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2023-2282 advisory.

  - Non-random values for ticket_age_add in session tickets in crypto/tls before Go 1.17.11 and Go 1.18.3
    allow an attacker that can observe TLS handshakes to correlate successive connections by comparing ticket
    ages during session resumption. (CVE-2022-30629)

  - An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server
    connections contain a cache of HTTP header keys sent by the client. While the total number of entries in
    this cache is capped, an attacker sending very large keys can cause the server to allocate approximately
    64 MiB per open connection. (CVE-2022-41717)

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