Restrict access to TCP ports 139 and 445 at the network perimeter. Grant access for trusted hosts and networks only.

Implement multiple redundant layers of security.
An attackers ability to exploit this vulnerability, to execute arbitrary code, may be hindered through the use of various memory protection schemes. Where possible, implement the use of non-executable and randomly mapped memory segments.

Microsoft has released an advisory (MS05-011) and updates to address this issue.
