Description Jan Lieskovsky 2013-03-12 09:35:16 EDT 
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.
