The hotfix for MS06-042, which was supposed to be released today, has been delayed. Worse: It turns out that MS06-042 introduced a new security problem.

In particular, note that MSFT's advisory essentially tells you how to exploit the issue. Exploits will likely follow very soon (days?).
At this point, we recommend:
