DESCRIPTION:
Behrang Fouladi has reported a vulnerability in Interaction SIP
Proxy, which can be exploited by malicious people to cause a DoS
(Denial of Service).

The vulnerability is caused due to a boundary error in "i3sipmsg.dll"
when handling SIP requests. This can be exploited to cause a
heap-based buffer overflow by sending an SIP version number with an
overly long sequence of space or TAB characters in a REGISTER
request.

The vulnerability has been reported in version 3.0.010. Prior
versions may also be affected.

SOLUTION:
Update to version 3.0.011.
