issue2550925 strip HTTP_PROXY environment variable
if deployed as CGI and client sends an http PROXY
header, the tainted HTTP_PROXY environment variable is created. It
can affect calls using requests package or curl. A roundup admin
would have to write detectors/extensions that use these mechanisms.
Not exploitable in default config.
