Update to Asterisk 1.8.32.1: this is a security fix release.

The Asterisk Development Team has announced security releases for Certified
Asterisk 1.8.28 and 11.6 and Asterisk 1.8, 11, 12, and 13. The available
security releases are released as versions 1.8.28-cert3, 11.6-cert8, 1.8.32.1,
11.14.1, 12.7.1, and 13.0.1.

The release of these versions resolves the following security vulnerabilities:

* AST-2014-012: Unauthorized access in the presence of ACLs with mixed IP
  address families

  Many modules in Asterisk that service incoming IP traffic have ACL options
  ("permit" and "deny") that can be used to whitelist or blacklist address
  ranges. A bug has been discovered where the address family of incoming
  packets is only compared to the IP address family of the first entry in the
  list of access control rules. If the source IP address for an incoming
  packet is not of the same address as the first ACL entry, that packet
  bypasses all ACL rules.

* AST-2014-018: Permission Escalation through DB dialplan function

  The DB dialplan function when executed from an external protocol, such as AMI,
  could result in a privilege escalation. Users with a lower class authorization
  in AMI can access the internal Asterisk database without the required SYSTEM
  class authorization.

For more information about the details of these vulnerabilities, please read
security advisories AST-2014-012, AST-2014-013, AST-2014-014, AST-2014-015,
AST-2014-016, AST-2014-017, and AST-2014-018, which were released at the same
time as this announcement.
