Security Bulletin: Microsoft Internet Explorer Zero-Day Vulnerability
What is it?
A critical vulnerability in Microsoft Internet Explorer (IE) may allow attackers to execute code on a computer if the user visits a malicious web site.
Who is impacted?
Any Microsoft Windows system that uses Internet Explorer to access the Internet is at risk. This includes all versions of Internet Explorer from IE6 through IE11.
What should you do?
There are several options available, each with varying degrees of difficulty. Depending on feasibility, you should:
- Stop using Internet Explorer and use an alternative browser. This may not be possible for individuals that rely on web services that use ActiveX, SharePoint, or other Microsoft technologies.
- Stop using Internet Explorer for browsing the Internet, and use IE only with specific sites that you trust. There are several methods available for configuring security options in IE to support this, such as whitelisting.
- Use more restrictive security settings in IE. The Security Zones in IE may be used to restrict what untrusted sites are allowed to do. Preventing script execution for such sites may help protect your system.
Generally speaking and especially in light of this vulnerability, it is not advisable to browse the Internet while you are logged into a system with administrative credentials.
