MS Security Hole In VPC

"A security vulnerability exists in Microsoft Virtual PC for Mac. The vulnerability exists because of the method by which Virtual PC for Mac creates a temporary file when you run Virtual PC for Mac. An attacker could exploit this vulnerability by inserting malicious code into the file which could cause the code to be run with system privileges. This could give the attacker complete control over the system. To exploit this vulnerability, an attacker would have to already have a valid logon account on the local system, or the attacker would already have to have access to a valid logon account. "
