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
