Much is being written about the XML Core Services vulnerability in all flavors of Windows.  The Internet Storm Center and Sophos are reporting that this is being actively exploited in the wild.  In light of the fact that Microsoft hasn't published a hotfix yet, does Symantec offer PTP definitions to protect against this specific threat with SEP 11 or 12?  We're debating on deploying the workaround but it would be great to know that we're already protected!
