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.
