Yesterday, Microsoft published its advance notification of the security bulletins scheduled to be released next Tuesday. In all, the list contains 13 updates, some of which will be listed as Critical. If you’re set up to receive Automatic Updates, you’ll get them without any extra steps. (And if you’re not set up for Automatic Updates, change your settings!)
The most interesting item on the list, at least to me, was a single Critical Update that affects Windows Media Player and MSN Messenger. I’m hoping this update will fix the problem with “poisoned” Windows Media files (see the discussion here, here, here, and here), but we won’t know until the patch is officially released.
