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. For more information about the details of these vulnerabilities, please read security advisories AST-2012-004, AST-2012-005, and AST-2012-006, which were released at the same time as this announcement.
