This security update resolves vulnerabilities in Internet Explorer. The more severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited these vulnerabilities could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
- Internet Explorer 11
- Internet Explorer 10
- Internet Explorer 9
- Internet Explorer 8
- Internet Explorer 7
The security update addresses the following vulnerabilities:
- Scripting Engine Memory Corruption Vulnerability - CVE-2016-0002
- Internet Explorer Elevation of Privilege Vulnerability - CVE-2016-0005
These vulnerabilities could allow remote code execution or an elevation of privilege if a user views a specially crafted webpage in Internet Explorer.

Depending on the privileges associated with the user, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights.
- After appropriate testing, apply appropriate patches provided by Microsoft to vulnerable systems.
- Consider implementing the workarounds provided by Microsoft if patching cannot be completed immediately, see the Microsoft link in the references section below.
- Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
- Remind users not to visit untrusted websites or follow links provided by unknown or untrusted sources.
