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.
