+ * Certified Asterisk 11.6-cert7 Released.
+
+ * AST-2014-011: Fix POODLE security issues
+
+ There are two aspects to the vulnerability:
+ (1) res_jabber/res_xmpp use SSLv3 only. This patch updates the module
+ to use TLSv1+. At this time, it does not refactor res_jabber/
+ res_xmpp to use the TCP/TLS core, which should be done as an
+ improvement at a latter date.
+ (2) The TCP/TLS core, when tlsclientmethod/sslclientmethod is left
+ unspecified, will default to the OpenSSL SSLv23_method. This
+ method allows for all encryption methods, including SSLv2/SSLv3.
+ A MITM can exploit this by forcing a fallback to SSLv3, which
+ leaves the server vulnerable to POODLE. This patch adds WARNINGS
+ if a user uses SSLv2/SSLv3 in their configuration, and explicitly
+ disables SSLv2/SSLv3 if using SSLv23_method.
+
+ For TLS clients, Asterisk will default to TLSv1+ and WARN if SSLv2 or
+ SSLv3 is explicitly chosen. For TLS servers, Asterisk will no longer
+ support SSLv2 or SSLv3.
+
+ Much thanks to abelbeck for reporting the vulnerability and providing
+ a patch for the res_jabber/res_xmpp modules.

=== UPGRADE-10.txt -- Upgrade info for 1.8 to 10
===
===========================================================
+
+from 11.6-cert6 to 11.6-cert7:
+
+* Due to the POODLE vulnerability (see
+ https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3566), the
+ default TLS method for TLS clients will no longer allow SSLv3. As
+ SSLv2 was already deprecated, it is no longer allowed by default as
+ well. TLS servers no longer allow SSLv2 or SSLv3 connections. This
+ affects the chan_sip channel driver, AMI, and the Asterisk HTTP server.
+
+* The res_jabber resource module no longer uses SSLv3 to connect to an
+ XMPP server. It will now only use TLSv1 or later methods.
From 11.6-cert2 to 11.6-cert3:
* MixMonitor AMI actions now require users to have authorization classes.
