The Asterisk Development Team has announced a security release for
Asterisk 11, Asterisk 11.1.2. This release addresses the security
vulnerabilities reported in AST-2012-014 and AST-2012-015, and
replaces the previous version of Asterisk 11 released for these
security vulnerabilities. The prior release left open a vulnerability
in res_xmpp that exists only in Asterisk 11; as such, other versions
of Asterisk were resolved correctly by the previous releases.

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

The release of these versions resolve the following two issues :

- Stack overflows that occur in some portions of Asterisk
that manage a TCP connection. In SIP, this is
exploitable via a remote unauthenticated session; in
XMPP and HTTP connections, this is exploitable via
remote authenticated sessions. The vulnerabilities in
SIP and HTTP were corrected in a prior release of
Asterisk; the vulnerability in XMPP is resolved in this
release.

- A denial of service vulnerability through exploitation
of the device state cache. Anonymous calls had the
capability to create devices in Asterisk that would
never be disposed of. Handling the cachability of device
states aggregated via XMPP is handled in this release.

These issues and their resolutions are described in the security
advisories.

For more information about the details of these vulnerabilities,
please read security advisories AST-2012-014 and AST-2012-015.

for having to do this twice!
