CVE-2013-2503 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:15.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream privoxy package and not the privoxy package as distributed by Ubuntu.
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.
