"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0099 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

      CVE-2022-27664:
      A flaw was found in the golang package. In net/http in Go, attackers can cause a denial of service
    because an HTTP/2 connection can hang during closing if a fatal error preempts the shutdown.
      CVE-2022-1705:
      A flaw was found in golang. The HTTP/1 client accepted invalid Transfer-Encoding headers indicating
    chunked encoding. This issue could allow request smuggling, but only if combined with an intermediate
    server that also improperly accepts the header as invalid.
      CVE-2022-32148:
      A flaw was found in net/http/httputil golang package. When httputil.ReverseProxy.ServeHTTP is called
    with a Request.Header map containing a nil value for the X-Forwarded-For header, ReverseProxy could set
    the client IP incorrectly. This issue may affect confidentiality.
      CVE-2022-30631:
      A flaw was found in golang. Calling the Reader, Read method on an archive that contains a large number
    of concatenated 0-length compressed files can cause a panic issue due to stack exhaustion.
      CVE-2022-30630:
      A flaw was found in the golang standard library, io/fs. Calling Glob on a path that contains a large
    number of path separators can cause a panic issue due to stack exhaustion. This could allow an attacker to
    impact availability.
      CVE-2022-30632:
      A flaw was found in golang. Calling Glob on a path that contains a large number of path separators can
    cause a panic issue due to stack exhaustion. This can cause an attacker to impact availability.
      CVE-2022-30635:
      A flaw was found in golang. When calling Decoder, Decode on a message that contains deeply nested
    structures, a panic can occur due to stack exhaustion and allows an attacker to impact system
    availability.

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