   An update that contains security fixes can now be installed.

Description:


   The Apache2 webserver was updated to fix various issues.

   The following feature was added:

       * Provide support for the tunneling of web socket connections to a
         backend websockets server. (FATE#316880)

   The following security issues have been fixed:

       * CVE-2013-5704: The mod_headers module in the Apache HTTP Server
         2.2.22 allowed remote attackers to bypass "RequestHeader unset"
         directives by placing a header in the trailer portion of data sent
         with chunked transfer coding. The fix also adds a "MergeTrailers"
         directive to restore legacy behavior.
       * CVE-2014-3581: The cache_merge_headers_out function in
         modules/cache/cache_util.c in the mod_cache module in the Apache
         HTTP Server allowed remote attackers to cause a denial of service
         (NULL pointer dereference and application crash) via an empty HTTP
         Content-Type header.
       * CVE-2003-1418: Apache HTTP Server allowed remote attackers to obtain
         sensitive information via (1) the ETag header, which reveals the
         inode number, or (2) multipart MIME boundary, which reveals child
         process IDs (PID). We so far assumed that this not useful to
         attackers, the fix is basically just reducing potential information
         leaks.

   The following bugs have been fixed:

       * Treat the "server unavailable" condition as a transient error with
         all LDAP SDKs. (bsc#904427)
       * Fixed a segmentation fault at startup if the certs are shared across
         > 1 server_rec. (bsc#907339)
