Please be specific. Preliminary IMA patches are out on the mailing lists. The only thing that IMA does with respect to existing known buffer overruns is that it enables remote parties to know that there is an application with a known buffer overrun if this application/script was measured. Such information is sensitive and this is one reason why direct access to the measurements are restricted to authorized/trusted parties.
