Run all software as a nonprivileged user with minimal access rights. Run the web client as an unprivileged user with minimal access rights. This will limit the impact of latent vulnerabilities.
Do not follow links provided by unknown or untrusted sources. Users should refrain from visiting sites of questionable integrity.
Set web browser security to disable the execution of script code or active content. Disabling scripting and active content in the Internet Zone may limit exposure to this and other vulnerabilities.
Implement multiple redundant layers of security.
Various memory-protection schemes (such as non-executable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.
Microsoft has released security advisory MS06-071 addressing this issue in supported versions of affected applications. Please see the references for more information.
