Synopsis

The remote Fedora host is missing a security update.

Description

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.
