MS13-051：Microsoft Office の脆弱性により、リモートでコードが実行される (2839571)

This security update resolves one reported vulnerability in Microsoft Office. The vulnerability could allow remote code execution if a user opens a maliciously-crafted Office document using anvulnerable version of Microsoft Office software, or previews or opens a maliciously-crafted email message in Outlook while using Microsoft Word as the email reader. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user, and thus take control of the system.
