Date Discovered October 9, 2007
Description Microsoft Internet Explorer is prone to a remote code-execution vulnerability.
An attacker may exploit this issue by enticing victims into viewing maliciously crafted HTML content.
Successfully exploiting this issue allows arbitrary machine code to execute in the context of the affected application. This facilitates the remote compromise of affected computers.

Run all software as a nonprivileged user with minimal access rights. To reduce the impact of latent vulnerabilities, always run nonadministrative 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. 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 nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.
Review and adjust according to policy any default configuration settings.
To limit the possibility of remote exploits through email, configure email client applications to view messages as plain text.
Microsoft has released a security bulletin and fixes to address this issue. Please see the references for more information.
