Do not accept or execute files from untrusted or unknown sources.
Malicious media files may be sent via email, hosted on a web page, or sent through instant messaging or other means. Never accept or open any files that originate from an untrusted source.
Do not follow links provided by unknown or untrusted sources.
Do not visit sites of questionable integrity, especially if solicited to do so by an untrusted or unfamiliar source.
Implement multiple redundant layers of security.
Memory-protection schemes such as nonexecutable stack/heap configurations and randomly mapped memory segments may complicate exploits of memory-corruption vulnerabilities.
Run all software as a nonprivileged user with minimal access rights.
Ensure that all nonadministrative tasks, such as browsing the web and reading email, are performed as an unprivileged user with minimal access rights.
Microsoft has released updates and an advisory to address this issue. Please see the references for more information.
