Asterisk 1.6.2.24, 1.8.11.1, 10.3.1 Now Available (Security Release)

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.

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

Asterisk 1.4.44, 1.6.2.23, 1.8.10.1, 10.2.1 Now Available (Security Releases)

The Asterisk Development Team has announced security releases for Asterisk 1.4,
1.6.2, 1.8, and 10. The available security releases are released as versions
1.4.44, 1.6.2.23, 1.8.10.1, and 10.2.1.

These releases are available for immediate download at
http://downloads.asterisk.org/pub/telephony/asterisk/releases

The release of Asterisk 1.4.44 and 1.6.2.23 resolve an issue wherein app_milliwatt
can potentially overrun a buffer on the stack, causing Asterisk to crash. This
does not have the potential for remote code execution.

The release of Asterisk 1.8.10.1 and 10.2.1 resolve two issues. First, they
resolve the issue in app_milliwatt, wherein a buffer can potentially be overrun
on the stack, but no remote code execution is possible. Second, they resolve
an issue in HTTP AMI where digest authentication information can be used to
overrun a buffer on the stack, allowing for code injection and execution.

These issues and their resolution are described in the security advisory.

For more information about the details of these vulnerabilities, please read the
security advisories AST-2012-002 and AST-2012-003, which were released at the same
time as this announcement.
