Revision Note: V1.0 (February 14, 2012): Bulletin published.
Summary: This security update resolves a privately reported vulnerability and a publicly disclosed vulnerability in Microsoft Windows. The more severe of these vulnerabilities could allow remote code execution if a user visits a website containing specially crafted content or if a specially crafted application is run locally. An attacker would have no way to force users to visit a malicious website. Instead, an attacker would have to convince users 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.
