libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if
thehost name is provided with a trailing dot.curl can be told to receive
and send cookies. curl’s “cookie engine” can bebuilt with or without
Public Suffix Listawareness. If PSL support
not provided, a more rudimentary check exists to atleast prevent cookies
from being set on TLDs. This check was broken if thehost name in the URL
uses a trailing dot.This can allow arbitrary sites to set cookies that then
would get sent to adifferent and unrelated site or domain.
