Security database references:
In Mitre's CVE dictionary: CVE-2016-5387.
More information:

Scott Geary of VendHQ discovered that the Apache HTTPD server used the value of the Proxy header from HTTP requests to initialize the HTTP_PROXY environment variable for CGI scripts, which in turn was incorrectly used by certain HTTP client implementations to configure the proxy for outgoing HTTP requests. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a CGI script to an attacker-controlled proxy via a malicious HTTP request.

For the stable distribution (jessie), this problem has been fixed in version 2.4.10-10+deb8u5.

We recommend that you upgrade your apache2 packages.
