Summary: Security update for apache2

Details: 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) - Ignore SIGINT signal in child processes. This fixes a race condition in signals handling when httpd is running on foreground and the user hits ctrl+c. (bsc#970391) - Don't put the backend in error state (by default) when 500/503 is overridden. (bsc#951692) - Remove obsolete /usr/share/apache2/rc.apache2 sample script. (bsc#973381)
