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

  - The Apache HTTP Server, when accessed through a TCP connection with a large window size, allows remote
    attackers to cause a denial of service (network bandwidth consumption) via a Range header that specifies
    multiple copies of the same fragment. NOTE: the severity of this issue has been disputed by third parties,
    who state that the large window size required by the attack is not normally supported or configured by the
    server, or that a DDoS-style attack would accomplish the same goal (CVE-2007-0086)

Note that Nessus relies on the presence of the package as reported by the vendor.");
