   An update that fixes two vulnerabilities is now available.

Description:

   This update for apache2 fixes the following issues:

   Security issues fixed:

   - CVE-2016-8743: Fixed liberal whitespace interpretation accepted from
     requests and sent in response lines and headers. Accepting these
     different behaviors represented a security concern when httpd
     participates in any chain of proxies or interacts with back-end
     application servers, either through mod_proxy or using conventional CGI
     mechanisms, and may result in request smuggling, response splitting and
     cache pollution. (bsc#1016715)
   - CVE-2016-4975: Fixed possible CRLF injection allowing HTTP response
     splitting attacks for sites which use mod_userdir. This issue was
     mitigated by changes which prohibit CR or LF injection into the
     "Location" or other outbound header key or value. (bsc#1104826)
