messages in Asterisk.

An additional change was backported, which is fully described in
http://downloads.asterisk.org/pub/security/AST-2013-007.html

With the fix for AST-2013-007, a new configuration option was added in
order to allow the system administrator to disable the expansion
of'dangerous' functions (such as SHELL()) from any interface which is
not the dialplan. In stable and oldstable this option is disabled by
default. To enable it add the following line to the section
'[options]' in /etc/asterisk/asterisk.conf (and restart asterisk)

live_dangerously = no"
