From ${URL} :

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.

net-proxy, is =net-proxy/privoxy-3.0.21 ready for stabilization?
Comment 2 Tom Wijsman (TomWij) (RETIRED) gentoo-dev 2013-03-14 12:47:00 UTC 
This was just added yesterday so this has not been tested thoroughly yet. We might want to wait a minimal amount of days to see if no bugs arise, let's wait until the start of next week at least before stabilizing this version.
