A security update for Internet Explorer has been released to address three remote code execution vulnerabilities.

Detailed Description

Microsoft has released a cumulative security update for Internet Explorer (IE) following reports on three discovered vulnerabilities. The vulnerabilities were all caused by a memory corruption condition that resulted from IE trying to access an uninitialized or a deleted object. Upon successful exploitation, an attacker may be able to execute code and take control of an affected system.

The update resolves these issues by introducing some modifications in the way that IE handles objects in memory. Users are recommended to install the latest update as a protection measure against possible exploit attempts.
