   Log Message:
   Update to Asterisk 11.1.2:  this is a security update for AST-2012-014
   and AST-2012-015.  Apparently the last update didn't completely
   fix the issues.

   The Asterisk Development Team has announced a security release for
   Asterisk 11, Asterisk 11.1.2. This release addresses the security
   vulnerabilities reported in AST-2012-014 and AST-2012-015, and
   replaces the previous version of Asterisk 11 released for these
   security vulnerabilities. The prior release left open a vulnerability
   in res_xmpp that exists only in Asterisk 11; as such, other versions
   of Asterisk were resolved correctly by the previous releases.

   The release of these versions resolve the following two issues:

   * Stack overflows that occur in some portions of Asterisk that manage a TCP
     connection. In SIP, this is exploitable via a remote unauthenticated session;
     in XMPP and HTTP connections, this is exploitable via remote authenticated
     sessions. The vulnerabilities in SIP and HTTP were corrected in a prior
     release of Asterisk; the vulnerability in XMPP is resolved in this release.

   * A denial of service vulnerability through exploitation of the device state
     cache. Anonymous calls had the capability to create devices in Asterisk that
     would never be disposed of. Handling the cachability of device states
     aggregated via XMPP is handled in this release.

   These issues and their resolutions are described in the security advisories.

   For more information about the details of these vulnerabilities, please read
   security advisories AST-2012-014 and AST-2012-015.

   For a full list of changes in the current release, please see the ChangeLog:

   Thank you for your continued support of Asterisk - and we apologize for having
   to do this twice!
