"The remote Redhat Enterprise Linux 9 host has one or more packages installed that are affected by multiple
vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - golang: net/http/httputil: ReverseProxy should not forward unparseable query parameters (CVE-2022-2880)

  - In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because
    an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. (CVE-2022-27664)

  - Large handshake records may cause panics in crypto/tls. Both clients and servers may send large TLS
    handshake records which cause servers and clients, respectively, to panic when attempting to construct
    responses. This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption
    (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client
    certificates (by setting Config.ClientAuth >= RequestClientCert). (CVE-2022-41724)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package
is installed.");
