Internet Explorer Vulnerability
An unpatched vulnerability in Microsoft's XML Core Services is currently being exploited via Internet Explorer. This flaw can expose Windows users to remote code execution attacks with little or no user action: inadvertently visiting a malicious website would be enough. Note that while web-based exploitation seems to be the most common form of attack for this vulnerability at present, it can also be exploited by convincing a victim to open a malicious file using Microsoft Office. While there is no patch available yet, Microsoft has issued a Fix it solution as a workaround for this vulnerability.
