In a blatant reminder of how important it is to keep a machine up to date, Symantec is reporting that attempts to exploit a particular Windows flaw are now being seen in the wild. The GDI flaw that was actually patched last week is now being targeted, with Symantec asserting that some of the attacks are successful, indicating that many machines are not yet patched.
Updates are often a double-edged sword, as we saw just earlier today or in recent history. The alternative to updating, having a machine compromised, isn't much better. The threat is not significant, but is still considered to be a problem.
