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

  - The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host
    header can inject additional headers or entire requests. With fix, the HTTP/1 client now refuses to send
    requests containing an invalid Request.Host or Request.URL.Host value. (CVE-2023-29406)
