Description: 

Multiple vulnerabilities have been discovered in Microsoft's web browser, Internet Explorer. The most severe of these vulnerabilities could allow remote code execution if a user views a specially crafted page in Internet Explorer. This update modifies the way Internet Explorer handles objects in memory, adds additional permission validations within Internet Explorer, and helps ensures that the ALSR security feature is properly implemented and cross-domain policies are properly enforced in Internet Explorer.

An attacker who successfully exploits some of these vulnerabilities could gain the same user rights as the current user. 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.

Actions: 

We recommend the following actions be taken:

  • Apply appropriate patches provided by Microsoft to vulnerable systems immediately after appropriate testing.
  • 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 un-trusted websites or follow links provided by unknown or un-trusted sources.
