    Multiple vulnerabilities have been discovered in Apache. Please review
      the CVE identifiers, upstream Apache Software Foundation documentation,
      and HTTPoxy website referenced below for details.
  
Impact :

    A remote attacker could cause a Denial of Service condition via multiple
      vectors or response splitting and cache pollution. Additionally, an
      attacker could intercept unsecured (HTTP) transmissions via the HTTPoxy
      vulnerability.
  
Workaround :

    There is no known workaround at this time."

"According to its banner, the version of Apache 2.4.x running on the
remote host is prior to 2.4.12. It is, therefore, affected by the
following vulnerabilities :

  - A flaw exists in module mod_headers that can allow HTTP
    trailers to replace HTTP headers late during request
    processing, which a remote attacker can exploit to
    inject arbitrary headers. This can also cause some
    modules to function incorrectly or appear to function
    incorrectly. (CVE-2013-5704)

  - A NULL pointer dereference flaw exists in module
    mod_cache. A remote attacker, using an empty HTTP
    Content-Type header, can exploit this vulnerability to
    crash a caching forward proxy configuration, resulting
    in a denial of service if using a threaded MPM.
    (CVE-2014-3581)

  - A out-of-bounds memory read flaw exists in module
    mod_proxy_fcgi. An attacker, using a remote FastCGI
    server to send long response headers, can exploit this
    vulnerability to cause a denial of service by causing
    a buffer over-read. (CVE-2014-3583)

  - A flaw exists in module mod_lua when handling a
    LuaAuthzProvider used in multiple Require directives
    with different arguments. An attacker can exploit this
    vulnerability to bypass intended access restrictions.
    (CVE-2014-8109)

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