"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-cert4, 1.8.13.1,
10.5.2, and 10.5.2-digiumphones.

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

The release of Asterisk 1.8.11-cert4, 1.8.13.1, 10.5.2, and
10.5.2-digiumphones resolve the following two issues :

  - If Asterisk sends a re-invite and an endpoint responds
    to the re-invite with a provisional response but never
    sends a final response, then the SIP dialog structure is
    never freed and the RTP ports for the call are never
    released. If an attacker has the ability to place a
    call, they could create a denial of service by using all
    available RTP ports.

  - If a single voicemail account is manipulated by two
    parties simultaneously, a condition can occur where
    memory is freed twice 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-2012-010 and AST-2012-011, which
were released at the same time as this announcement.
