+
+If a URL is given with a zero-length host name, like in "http://:80" or
+just ":80", `fix_hostname()` will index the host name pointer with a -1
+offset (as it blindly assumes a non-zero length) and both read and

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The internal libcurl function called sanitize_cookie_path() that cleans
+up the path element as given to it from a remote site or when read from
+a file, did not properly validate the input. If given a path that
+consisted of a single double-quote, libcurl would index a newly
+allocated memory area with index -1 and assign a zero to it, thus
+destroying heap memory it wasn't supposed to.

+Subject: [PATCH] http_done: close Negotiate connections when done
+
+When doing HTTP requests Negotiate authenticated, the entire connnection
+may become authenticated and not just the specific HTTP request which is
+otherwise how HTTP works, as Negotiate can basically use NTLM under the
+hood. curl was not adhering to this fact but would assume that such
+requests would also be authenticated per request.
