Multiple vulnerabilities have been discovered in Microsoft's web browser, Internet Explorer, the most severe of these could result in remote code execution. Successful exploitation can occur when a user visits a specially crafted website. There are twenty-four vulnerabilities when Internet Explorer improperly accesses objects in memory and two elevation of privilege vulnerabilities. An attacker who successfully exploits some of these vulnerabilities could gain the same user rights as the current user.

Actions: 

We recommend the following actions be taken:

  • Apply appropriate patches provided by Microsoft to vulnerable systems immediately after appropriate testing.
