    Microsoft confirmed Saturday that it is working to fix the code that allows Internet Explorer versions six through 11 to be exploited by the vulnerability. As of Monday morning, no fix had been posted. Computer users who are running the Windows XP operating system are out of luck.

    I wonder when MS is going to suck it up and leave EPM (Enhanced Protected Mode) on by default, which mitigates this issue. Here's hoping with IE12...

    Also integrate EMET into the Windows control panel, which also mitigates this issue.

    No one using XP should be using IE.

    Thus, to immediately protect any use of Internet Explorer on 32-bit versions only of Windows – yes, even on creaky old WinXP (the XPocalypse has been delayed) – simply copy the following incantation, then paste and run it in either a Windows Command Prompt or the “Run…” dialog under the Start button (if you’re lucky enough to still have one on your Windows desktop):

    regsvr32 -u "%CommonProgramFiles%\Microsoft Shared\VGX\vgx.dll"
    This unregisters (-u) the VML renderer, thus rendering it inaccessible to the exploit attempt. Your IE browser will no longer be able to render vector markup language content… but it probably never did before, anyway.

    You can perform a “before and after” test to confirm that VML rendering has been disabled with this simple VML rendering of an office layout: http://www.vmlmaker.com/gallery/visio/office_layout.htm. Note that Internet Explorer must be restarted after making any change.

    From what I understand, we shouldn't confuse the Flash Player update KB2961887 with a solution for the zero-day exploit. They just coincidentally happened at the same time.

    Yes Flash player was used to trigger IE's zero day exploit. Updating Flash won't close browser's zero day. Flash has been updated, we're still waiting for update for IE.

    EMET protects against this if you have Deep Hooks and Anti-detour enabled. If you use EMET 5.0 TP, the new ASR will also provide protection.
    http://blogs.technet.com/b/srd/arch...-about-security-advisory-2963983-ie-0day.aspx
    MS will soon release EMET 4.1 update 1 which will have Deep Hooks enabled by default.

    Unregistering vgx.dll does not guarantee protection against exploitation!

    maybe it would interfere with the install of addons?

    anyway, I got both EPM and 64 bits EPM running.

    IE itself run at medium Integrity Level.
    with only one tab open the sub-process runs at AppContainer IL.
    which is stricter than low IL I gather.
