Log Message:
Update to Asterisk 11.21.1:  this is mainly a bug patch update plus
fixes for AST-2016-001, AST-2016-002, and AST-2016-003.  Also some
pkglinting.

----- 11.21.1

The Asterisk Development Team has announced security releases for Certified
Asterisk 11.6 and 13.1 and Asterisk 11 and 13. The available security releases
are released as versions 11.6-cert12, 11.21.1, 13.1-cert3, and 13.7.1.

The release of these versions resolves the following security vulnerabilities:

* AST-2016-001: BEAST vulnerability in HTTP server

  The Asterisk HTTP server currently has a default configuration which allows
  the BEAST vulnerability to be exploited if the TLS functionality is enabled.
  This can allow a man-in-the-middle attack to decrypt data passing through it.

* AST-2016-002: File descriptor exhaustion in chan_sip

  Setting the sip.conf timert1 value to a value higher than 1245 can cause an
  integer overflow and result in large retransmit timeout times. These large
  timeout values hold system file descriptors hostage and can cause the system
  to run out of file descriptors.

* AST-2016-003: Remote crash vulnerability receiving UDPTL FAX data.

  If no UDPTL packets are lost there is no problem. However, a lost packet
  causes Asterisk to use the available error correcting redundancy packets. If
  those redundancy packets have zero length then Asterisk uses an uninitialized
  buffer pointer and length value which can cause invalid memory accesses later
  when the packet is copied.
