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-cert2, 1.8.12.1, and 10.4.1.
These releases are available for immediate download at http://downloads.asterisk.org/pub/telephony/asterisk/releases
The release of Asterisk 1.8.11-cert2, 1.8.12.1, and 10.4.1 resolve the following two issues :
- A remotely exploitable crash vulnerability exists in the IAX2 channel driver if an established call is placed on hold without a suggested music class. Asterisk will attempt to use an invalid pointer to the music on hold class name, potentially causing a crash.
- A remotely exploitable crash vulnerability was found in the Skinny (SCCP) Channel driver. When an SCCP client closes its connection to the server, a pointer in a structure is set to NULL. If the client was not in the on-hook state at the time the connection was closed, this pointer is later dereferenced. This allows remote authenticated connections the ability to cause a crash in the server, denying services to legitimate users.
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-2012-007 and AST-2012-008, which were released at the same time as this announcement.
