Update Information:

Common Vulnerabilities and Exposures assigned an identifier CVE-2013-2503
to the following vulnerability:

Privoxy before 3.0.21 does not properly handle Proxy-Authenticate and
Proxy-Authorization headers in the client-server data stream, which makes
it easier for remote HTTP servers to spoof the intended proxy service via a
407 (aka Proxy Authentication Required) HTTP status code.
