The remote SIP client is prone to a buffer overflow attack.
The version of SoftPhone installed on the remote host reportedly fails
to properly handle SIP packets with long 'a=' lines in the SDP data.
An unauthenticated, remote attacker may be able to exploit this flaw to
overflow a buffer and execute arbitrary code on the remote host.
