Fedora 16 : asterisk-1.8.11.1-1.fc16 (2012-6612)

Synopsis :

The remote Fedora host is missing a security update.

Description :

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.
