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.

Thank you for your continued support of Asterisk - and we apologize
for having to do this twice!

description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
