Description

When asked to use a `.netrc` file for credentials **and** to follow HTTP
redirects, curl could leak the password used for the first host to the
followed-to host under certain circumstances.

This flaw only manifests itself if the netrc file has a `default` entry that
omits both login and password. A rare circumstance.
