Pidgin 2.6.0 and prior does not follow the require TLS/SSL preference

oval:org.mitre.oval:def:5757

protocols/jabber/auth.c in libpurple in Pidgin 2.6.0 and possibly other versions does not follow the "require TLS/SSL" preference when connecting to older Jabber servers that do not follow the XMPP specification which causes libpurple to connect to the server without the expected encryption and allows remote attackers to sniff sessions.
