  script_tag(name:"insight", value:"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)");
