MS11-023：Microsoft Office の脆弱性により、リモートでコードが実行される (2489293)

This security update addresses two vulnerabilities in Microsoft Office, which could allow remote code execution. A remote malicious user could gain the same user rights as the logged on user if a user opens a specially crafted Office file. In addition, when a user opens a legitimate Office file located in the same network directory as a specially crafted library file, it could also allow remote code execution.
