None.
General blocking of network traffic triggering this event is not suggested as such data may be valid and acceptable in many contexts. Furthermore, the vulnerable mail client is not in widespread use, so catering to its security oversights generally does not warrant the suppression of mail traffic that would be otherwise be harmless.

Unauthorized Access Attempt
Microsoft Windows Vista could allow a remote attacker to execute local code on the system, caused by an error in the Mail Client. An attacker could exploit this vulnerability by sending a specially-crafted email message containing a malicious URL to execute local code on the vulnerable system, if the attacker could persuade the victim to open and authorize the malicious URL.
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS07-34. See References.
