Date Discovered November 8, 2013
Description Microsoft Windows is prone to a remote code-execution vulnerability.
Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the application (typically Internet Explorer) using the ActiveX control. Failed exploit attempts will likely result in denial-of-service conditions.

Run all software as a nonprivileged user with minimal access rights. When possible, run all software as a user with minimal privileges and limited access to system resources. Use additional precautions such as restrictive environments to insulate software that may potentially handle malicious content.
Deploy network intrusion detection systems to monitor network traffic for malicious activity. Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This may indicate exploit attempts or activity that results from successful exploits.
Do not follow links provided by unknown or untrusted sources. Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources.
Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
Implement multiple redundant layers of security.
Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.
Updates are available. Please see the references or vendor advisory for more information.
