This update for apache2 fixes the following issues:

* It used to be possible to set an arbitrary $HTTP_PROXY environment variable
  for request handlers -- like CGI scripts -- by including a specially crafted
  HTTP header in the request (CVE-2016-5387). As a result, these server
  components would potentially direct all their outgoing HTTP traffic through a
  malicious proxy server. This patch fixes the issue: the updated Apache server
  ignores such HTTP headers and never sets $HTTP_PROXY for sub-processes
  (unless a value has been explicitly configured by the administrator in the
  configuration file). (bsc#988488)
