Date Discovered December 12, 2006
Description Microsoft Internet Explorer is prone to a remote code-execution vulnerability.
This vulnerability is related to how the browser handles script errors. An attacker may exploit this vulnerability to execute arbitrary code in the context of the user running the affected browser.

Run all software as a nonprivileged user with minimal access rights. To reduce the impact of latent vulnerabilities, always run non-administrative software as an unprivileged user with minimal access rights.
Do not follow links provided by unknown or untrusted sources. Attackers could exploit this vulnerability by enticing a user to visit a malicious website. Do not follow links provided by sources of questionable integrity.
Set web browser security to disable the execution of script code or active content. Disable support for script code and active content within a client browser to reduce the chances of a successful exploit. Note that this mitigation tactic might adversely affect legitimate websites that rely on the execution of browser-based script code.
Implement multiple redundant layers of security.
Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as non-executable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.
Microsoft released a security bulletin and fixes to address this issue. Please see the references for more information.
