   An update that solves one vulnerability and has four fixes
   is now available. It includes one version update.

Description:


   This update brings Apache to version 2.2.12.

   The main reason is the enablement of the Server Name
   Indication (SNI) that  allows several SSL-enabled domains
   on one IP address (FATE#311973). See the
   SSLStrictSNIVHostCheck directive as documented in
   /usr/share/apache2/manual/mod/mod_ssl.html.en

   Also the patch for the ByteRange remote denial of service
   attack  (CVE-2011-3192) was refined and the configuration
   options used by upstream  were added.

   Introduce new config option: Allow MaxRanges Number of
   ranges requested, if exceeded, the complete content is
   served. default: 200 0|unlimited: unlimited none: Range
   headers are ignored. This option is a backport from 2.2.21.

   Also fixed were

   * CVE-2011-3348: Denial of service in proxy_ajp when
   using a undefined method.
   * CVE-2011-3368: Exposure of internal servers via
   reverse proxy methods with mod_proxy enabled and incorrect
   Rewrite or Proxy Rules.

   This update also includes a newer
   apache2-vhost-ssl.template, which  disables SSLv2, and
   allows SSLv3 and strong ciphers only. Please note that
   existing vhosts will not be converted.
