Microsoft fixes shortcut vulnerability - MS10-046

On Monday Microsoft released an out-of-band patch for the well-documented Windows shortcut vulnerability. The patch is called MS10-046 and will show up in Windows Update as "Security Update for Windows XXXX (KB2286198)".

Today on the MSRC blog, Microsoft posted an extensive Q&A about the patch that referenced our Windows Shortcut Exploit Protection Tool. The question was: "Do you know whether MS10-046 has any compatibility issues if the Sophos Windows Shortcut Exploit Protection Tool has already been installed?" I have done some testing with both Windows 7 and Windows XP SP3 and found that they are in no way incompatible.

I advise that you remove the Sophos tool and then immediately deploy MS10-046 on your workstations, but it should not break anything if you deploy the Microsoft fix first and then remove our tool. It is critical that you maintain continuous protection with either our tool or the Microsoft fix, as the EXP/CPLink identity is the 5th most common piece of malware we have seen in the last 24 hours.
