   An update that solves two vulnerabilities and has three
   fixes is now available.

Description:


   This update fixes a remote denial of service bug (memory
   exhaustion) in the  Apache 2 HTTP server, that could be
   triggered by remote attackers using  multiple overlapping
   Request Ranges. (CVE-2011-3192)

   It also fixes a issue in mod_dav, where the (1) mod_cache
   and (2) mod_dav  modules in the Apache HTTP Server 2.2.x
   allowed remote attackers to cause a  denial of service
   (process crash) via a request that lacks a path.
   (CVE-2010-1452)

   Also following bugs were fixed:

   * recommend the default MPM (prefork) via Recommends:
   in .spec
   * apache not sending error 304 if mod_deflate is
   enabled.
   * take LimitRequestFieldsize config option into account
   when parsing headers from backend.
