   An update that fixes one vulnerability is now available.

Description:


   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)
