Java/Script Alert: Cross-Platform Browser Vulnerability

Ant writes "Synopsis: Opera, Mozilla & Netscape with javascript enabled are vulnerable to remote command execution. This has been tested on Microsoft, and many many Unices. Macintosh may also be vuln. Ironically enough, IE is unaffected." Update: 06/08 23:56 GMT by H : The problem seems to be one in the Java security model itself; but the evidence seems to be that if you turn off JavaScript, you turn off the vulnerability. Update: 06/09 00:56 GMT by T : According to this followup message from Mozilla security group member Daniel Veditz, the problem is actually one that's already been fixed in Mozilla 1.3, and not a remote command execution vulnerability at all.
