File curl-CVE-2015-3148.patch of Package curl.28253
From 21b8c694881ce8a48121d6e0152e834ed3901e25 Mon Sep 17 00:00:00 2001 From: Daniel Stenberg <daniel@haxx.se> Date: Sat, 18 Apr 2015 23:50:16 +0200 Subject: [PATCH] http_done: close Negotiate connections if not 401 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. Bug: http://curl.haxx.se/docs/adv_20150422B.html Reported-by: Isaac Boukris commit f78ae415d24b9bd89d6c121c556e411fdb21c6aa Author: David Woodhouse <David.Woodhouse@intel.com> Date: Fri Jul 11 11:09:34 2014 +0100 Don't clear GSSAPI state between each exchange in the negotiation GSSAPI doesn't work very well if we forget everything ever time. XX: Is Curl_http_done() the right place to do the final cleanup?
