Update Information:

The Asterisk Development Team has announced a security release for Asterisk 10.
This security release is released as version 10.5.1.

The release is available for immediate download at
http://downloads.asterisk.org/pub/telephony/asterisk/releases

The release of Asterisk 10.5.1 resolves the following issue:

* A remotely exploitable crash vulnerability was found in the Skinny (SCCP)
 Channel driver. When an SCCP client sends an Off Hook message, followed by
 a Key Pad Button Message, a structure that was previously set to NULL is
 dereferenced.  This allows remote authenticated connections the ability to
 cause a crash in the server, denying services to legitimate users.

This issue and its resolution is described in the security advisory.

For more information about the details of this vulnerability, please read
security advisory AST-2012-009, which was released at the same time as this
announcement.

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

- The Asterisk Development Team has announced security releases for Certified
- Asterisk 1.8.11 and Asterisk 1.8 and 10. The available security releases are
- released as versions 1.8.11-cert2, 1.8.12.1, and 10.4.1.
-
- These releases are available for immediate download at
- http://downloads.asterisk.org/pub/telephony/asterisk/releases
-
- The release of Asterisk 1.8.11-cert2, 1.8.12.1, and 10.4.1 resolve the
following
- two issues:
-
- * A remotely exploitable crash vulnerability exists in the IAX2 channel
-  driver if an established call is placed on hold without a suggested music
-  class. Asterisk will attempt to use an invalid pointer to the music
-  on hold class name, potentially causing a crash.
-
- * A remotely exploitable crash vulnerability was found in the Skinny (SCCP)
-  Channel driver. When an SCCP client closes its connection to the server,
-  a pointer in a structure is set to NULL.  If the client was not in the
-  on-hook state at the time the connection was closed, this pointer is later
-  dereferenced. This allows remote authenticated connections the ability to
-  cause a crash in the server, denying services to legitimate users.
-
- 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-2012-007 and AST-2012-008, which were released at the
- same time as this announcement.
