"Dominic Scheirlinck and Scott Geary of Vend reported an insecure
behaviour in the lighttpd web server. Lighttpd assigned Proxy header
values from client requests to internal HTTP_PROXY environment
variables. This could be used to carry out Man in the Middle Attacks
(MIDM) or create connections to arbitrary hosts.

For Debian 7 'Wheezy', this issue has been fixed in version
1.4.31-4+deb7u5.

We recommend that you upgrade your lighttpd packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
