SUSE Security Update: Security update for apache2

______________________________________________________________________________
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)
