Changes with Apache 2.4.10

  *) SECURITY: CVE-2014-0117 (
     mod_proxy: Fix crash in Connection header handling which 
     allowed a denial of service attack against a reverse proxy
     with a threaded MPM.  [Ben Reser]

     Fix a memory consumption denial of service in the WinNT MPM (used in all Windows
     installations). Workaround: AcceptFilter <protocol> {none|connect}
     [Jeff Trawick]

  *) SECURITY: CVE-2014-0226 (
     Fix a race condition in scoreboard handling, which could lead to
     a heap buffer overflow.  [Joe Orton, Eric Covener]

  *) SECURITY: CVE-2014-0118 (
     mod_deflate: The DEFLATE input filter (inflates request bodies) now
     limits the length and compression ratio of inflated request bodies to avoid
     denial of sevice via highly compressed bodies.  See directives

     default, the client I/O timeout (Timeout directive) now applies to

     used to set a different timeout for communication with scripts.

     Joe Orton]

  *) mod_dav: Fix improper encoding in PROPFIND responses.  PR 56480.
     [Ben Reser]

  *) WinNT MPM: Improve error handling for termination events in child.
