The release of Asterisk,, and resolves several issues as outlined below :

- AST-2011-008: If a remote user sends a SIP packet containing a null, Asterisk assumes available data extends past the null to the end of the packet when the buffer is actually truncated when copied. This causes SIP header parsing to modify data past the end of the buffer altering unrelated memory structures. This vulnerability does not affect TCP/TLS connections. -- Resolved in and

- AST-2011-009: A remote user sending a SIP packet containing a Contact header with a missing left angle bracket (<) causes Asterisk to access a NULL pointer. -- Resolved in

- AST-2011-010: A memory address was inadvertently transmitted over the network via IAX2 via an option control frame and the remote party would try to access it. -- Resolved in,, and
