If you use Gaim for instant messaging, there’s a patch you need to grab for a recent vulnerabiilty. If you don’t compile Gaim yourself, check to see if there is an updated package for your Linux distro.
Just in case anyone at Yahoo happens to stumble over this page: Quit changing the bloody sign on or whatever. If I have to choose between using the “official” Yahoo client (which is clunkier than Gaim) or not using Yahoo for IM, I’ll simply choose not to use Yahoo. It’s annoying to be forced to use a different client for each IM protocol. It’s about time that AOL, Yahoo, MSN and all the other folks get together and learn to play nice. Geez.
