Security Vulnerability in Internet Explorer
April 28, 2014 (Updated May 5, 2014)
A very serious security flaw found in Internet Explorer allows hackers to take complete control of compromised machines. On May 1, Microsoft released a fix for Windows Vista, Windows 7, Windows 8, and even Windows XP—although Microsoft has firmly stated that this patch for XP is exceptional, and that users of XP are strongly encouraged to migrate off the now unsupported operating system. Please run Windows Update and install any critical updates if you haven't already.
Automatic updates should be enabled on your computer to ensure that repairs for security defects are installed as soon as they become available. To check or change your update settings visit the Microsoft Windows or Apple MacOS updating instructions.
WINDOWS XP USERS: This security defect is the first major flaw discovered since Microsoft discontinued support for Windows XP on April 8. As additional flaws are discovered, Windows XP will become an increasing risk for those still using it. It is critical that all Windows XP machines be upgraded to at least Windows 7 as soon as possible. If your department needs assistance with evaluating equipment for upgrade or replacement, contact IRT at firstname.lastname@example.org or 215-895-2020.
