Version2013-07-09
Severity Rating: Critical
Revision Note: V2.1 (July 9, 2013): Bulletin revised to announce a detection change that excludes Windows 7 language packs from the 2485376 update for Windows XP Professional x64 Edition Service Pack 2. This is a detection change only. Customers who have already successfully updated their systems do not need to take any action.
Summary: This security update resolves a privately reported vulnerability in the Windows OpenType Compact Font Format (CFF) driver. The vulnerability could allow remote code execution if a user views content rendered in a specially crafted CFF font. In all cases, an attacker would have no way to force users to view the specially crafted content. Instead, an attacker would have to convince users to visit a Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes users to the attacker's Web site.
