Hole could allow user's Windows PC to be infiltrated.
Microsoft has issued a fix for an Internet Explorer flaw that allowed hackers to infiltrate the browser's users' PC.
The fix is for a zero-day vulnerability found in older versions of Internet Explorer that could allow malicious hackers to gain control of Windows computers to host malicious web sites.
The company previously said that it was investigating a remote code execution vulnerability within IE 6, IE 7 and IE 8. Versions of the browser after Internet Explorer 8 are unaffected.
Microsoft detailed an update containing a one-click fix that prevents the vulnerability from being exploited without affecting the ability to browse the internet. The software giant added that the fix doesn't require users to perform a reboot.
It also said that the method was not intended to become a replacement for security updates. "While we have still observed only a few attempts to exploit this issue, we encourage all customers to apply this fix it to help protect their systems," said Dustin Childs, group manager for Microsoft's Trustworthy Computing.
