Descriptions

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.

Privoxy anterior a v3.0.21 no maneja adecuadamente las cabeceras Proxy-Authenticate y Proxy-Authorization en el flujo de datos del cliente, lo que facilita a servidores remotoso HTTP suplantar el servicio proxy establecido a través de un código de estado 407 (Aka Proxy Authentication Required)

Privoxy version 3.0.20-1 suffers from an authentication credential exposure vulnerability.
