Last week, Adobe made a fairly silent update to several versions of their Flash player. It seems that several security flaws were discovered in the players, affecting all three current generations of player: 7, 8 and 9. All the flaws are rated as critical, though very little was published about it before the fix.
One of the flaws, it seems, could be used to potentially log keystrokes. However, the flaw was isolated to the 7 series player, which has long since been replaced by versions 8 and 9. Regardless, those versions as well have independent flaws, making an update a good idea. If you are using the player, it's a good idea to update.
This is another cross-platform flaw, too, affecting Windows, Mac, Linux and Solaris. Adobe is recommending anyone using the players update immediately.
