TippingPoint IPS customers have been protected against this
vulnerability by Digital Vaccine protection filter ID 9315. 
For further product information on the TippingPoint IPS, visit:

-- Vulnerability Details:
This vulnerability allows remote attackers to potentially execute
arbitrary code on vulnerable installations of Microsoft Internet
Explorer. User interaction is required to exploit this vulnerability in
that the target must visit a malicious page.

The specific flaw exists during a race condition while repetitively
clicking between two elements at a fast rate. When clicking back and
forth between these two elements a corruption occurs resulting in a call
to a dangling pointer which can be further leveraged into code execution
via a heap spray. Exploitation of this vulnerability will lead to remote
system compromise under the credentials of the currently logged in user.

-- Vendor Response:
Microsoft has issued an update to correct this vulnerability. More
details can be found at:
