There’s a pretty nasty security vulnerability in Safari having to do with RSS feeds, the news of which is getting drowned out by all the inaugural hoopla, so I’m doing my bit to bang the drum. The details are here, but the bottom line is, if you’re on OSX 10.5, either stop using Safari or follow the step at the link, otherwise you’re risking the privacy of your data. If you don’t trust Mastenbrook’s info you can read up on the issue over on secunia as well.
