Description: Gary O'leary-Steele has reported a vulnerability in Microsoft Windows and Microsoft Exchange 2000 Server, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to a boundary error in the CDO (Collaboration Data Objects) COM component when event sinks are used to parse email contents. This can be exploited to cause a stack-based buffer overflow via a specially crafted email message with an overly long header line that is delivered through SMTP. Successful exploitation allows arbitrary code execution. Do you have this product installed on your home computer? Scan using the free Personal Software Inspector.
