Re: Protect Yourselves
The solution is quite simple. This IE exploit only affects user accounts with Administrative privileges.

In fact this has nothing to do with XP at all. Do not operate IE as an Administrator and you will be immune to this particular exploit.

However, a simple Metasploit attack vector can easily leverage to System privileges bypassing any security in place on an XP machine. That being said, XP = Instant PWN!

XP is broken. There is no way to harden IE or the OS itself.

Re: Protect Yourselves
No problem, I understand completely.  Many organizations have web apps that will only work on older versions of IE.  One way to mitigate this shortcoming is to use a application virtualization technology such as Citrix to sandbox IE.

Re: Workaround
Yes, if you must use a version of IE older than 10 then yes, disabling Flash should provide you with protection from the vulnerability.

Protect Yourselves
For anyone that must use IE to perform there daily work I highly recommend you enable Enable Enhanced Protected Mode (IE 10 and IE 11).  Otherwise my recommendation is to use another web browser until this bug is patched.  

This is taken directly from the advisory but it is important everyone is aware.

To enable EPM in Internet Explorer, perform the following steps:
  1. On the Internet Explorer Tools menu, click Internet Options.
  2. In the Internet Options dialog box, click the Advanced tab, and then scroll down to the Security section of the settings list.
  3. If you are running Internet Explorer 10, ensure the checkbox next to Enable Enhanced Protected Mode is selected.
  4. If you are running Internet Explorer 11, ensure the checkboxes next to Enable Enhanced Protected Mode and Enable 64-bit processes for Enhanced Protected Mode (for 64-bit systems) are selected.
  5. Click OK to accept the changes and return to Internet Explorer.
  6. Restart your system.

Workaround
If for some reason you had to use an older version of IE, would disabling Flash be helpful?
