Mozilla offers temporary fix for Firefox flaw. The patch protects against exploitation of a serious flaw by disabling the browser feature that contains the vulnerability. [CNET News.com]
If you run Firefox, which many of the visitors here do, you need to protect yourself against this vulernability in the way Firefox handles International Domain Names. This isn't the first time IDNs have been the root of a security problem (they still have a critical issue in the ability of nefarious agents to use IDNs for phishing purposes). Firefox is no longer a fringe browser, and has enough of a user-base that it is a likely target for criminal hackers.
