Navigator 3.0 beta release 4 remedies a security flaw in Netscape's support for Java, which was publicized over the weekend. The company is evaluating whether to provide a software patch for users of the 2.0 series of Navigator.
Officials say users have very little to worry about because the problem was so esoteric that it would have taken months of sleuthing by experts to uncover the problem in the first place.
The bug--the third discovered in the browser in recent months--was unearthed by researchers at Princeton University and has to do with Navigator's use of the Java programming language, which can create a security breach. Although the Princeton team was able to replicate the problem within its labs, no specific details were provided by either Netscape or the Princeton group.
