Microsoft releases seven security bulletins for January 2013. Two outline patches for critical vulnerabilities in XML Core Services and Windows print spooler components. In total, the seven updates address security holes in Windows, Office, Developer Tools, Server Software and theNET Framework. The most likely attack vector is a malicious webpage, but an email with Office document attachment can also be a viable alternative for attackers. The other critical update, MS13-001, addresses one privately reported vulnerability in Microsoft Windows. The vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer.”]
