Microsoft released a Security Advisory 980088 to address a publicly disclosed vulnerability in Internet Explorer that may allow Information Disclosure for customers running on Windows XP or who’ve disabled Internet Explorer Protected Mode. “Customers running Internet Explorer 7 or Internet Explorer 8 in their default configuration on Windows Vista or later operating systems are not vulnerable to this issue as they benefit from Internet Explorer Protected Mode, which protects from this issue. Windows XP users, or users who have disabled Protected Mode, can help protect themselves by implementing Network Protocol Lockdown. We’ve created a Microsoft Fix It to automate this. The Fix It can be run on individual systems or enterprises can deploy it through their automated systems,” says MSRC blog.
