Summary
Security update for apache2

Notes

Title of the patch
Security update for apache2
Description of the patch
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)
