    Package        : apache2
    CVE ID         : CVE-2016-5387
    
    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.
