Detail

Revision Note: V1.1 (July 9, 2013): Bulletin revised to announce a detection change in the Windows Vista packages for the 2706045 update to correct a Windows Update reoffering issue. 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 JScript and VBScript scripting engines on 64-bit versions of Microsoft Windows. The vulnerability could allow remote code execution if a user visited a specially crafted website. An attacker would have no way to force users to visit the 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 users to the attacker's website.
