A security hole in ISP America Online's instant messenger service, AIM, which may have let hackers gain access to thousands of subscribers' machines, has now been resolved.
"Users should not be concerned. There was a hole, which we have now fixed in our server," said AOL spokesman Andrew Weinstein. "There is no need to download any patches."
The hole, discovered by U.S. security firm w00w00, threatened to leave thousands of AOL's subscribers running the Windows version of AIM (all versions up to and including 4.7) open to attack. The flaw lay in the applications that allow users to add people to their buddy lists and play online games.
