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)");
