MS14-075：Microsoft Exchange Server の脆弱性により、特権が昇格される (3009712)

This security update resolves four privately reported vulnerabilities in Microsoft Exchange Server. The most severe of these vulnerabilities could allow elevation of privilege if a user clicks a specially crafted URL that takes them to a targeted Outlook Web App site. An attacker would have no way to force users to visit a specially crafted website. Instead, an attacker would have to convince them to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes them to the attacker's website, and then convince them to click the specially crafted URL.
