| The Asterisk Development Team has announced security releases for Asterisk 1.6.2, 1.8, and 10. The available security releases are released as versions 1.6.2.24,
 1.8.11.1, and 10.3.1.
 
 These releases are available for immediate download at
 http://downloads.asterisk.org/pub/telephony/asterisk/releases
 
 The release of Asterisk 1.6.2.24, 1.8.11.1, and 10.3.1 resolve the following two
 issues:
 
 * A permission escalation vulnerability in Asterisk Manager Interface.  This
 would potentially allow remote authenticated users the ability to execute
 commands on the system shell with the privileges of the user running the
 Asterisk application.
 
 * A heap overflow vulnerability in the Skinny Channel driver.  The keypad
 button message event failed to check the length of a fixed length buffer
 before appending a received digit to the end of that buffer.  A remote
 authenticated user could send sufficient keypad button message events that the
 buffer would be overrun.
 
 In addition, the release of Asterisk 1.8.11.1 and 10.3.1 resolve the following
 issue:
 
 * A remote crash vulnerability in the SIP channel driver when processing UPDATE
 requests.  If a SIP UPDATE request was received indicating a connected line
 update after a channel was terminated but before the final destruction of the
 associated SIP dialog, Asterisk would attempt a connected line update on a
 non-existing channel, causing a crash.
 
 These issues and their resolution are described in the security advisories.
 
 For more information about the details of these vulnerabilities, please read
 security advisories AST-2012-004, AST-2012-005, and AST-2012-006, which were
 released at the same time as this announcement.
