Another Out Of Band MS08-078

This is going to be short as it's already covered well elsewhere and this is late... Microsoft has another out-of-band patch as of 12/17, MS08-078 affecting all versions of IE on all supported OSes except Server 2008 for IA-32/x64. Zero-day exploits are already going on. Get this one patched ASAP.

I'd normally say "use Firefox" or some other browser whenever possible, but Firefox and Opera are also currently suffering vulnerabilities. Firefox 3.0.5 resolves the issues. While not quite as sever as the zero-day exploit on IE, these are noteworthy as cross-platform.
