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 :
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.

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.

please read security advisories AST-2012-004, AST-2012-005, and
AST-2012-006, which were released at the same time as this
