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.
