A.L. Digital Announce Java Hacks
--------------------------------

25th Feb 1997

A.L. Digital, in association with Ben Laurie and Major Malfunction, have
found
and exploited a loophole in Microsoft Internet Explorer V3.01.

In brief, this loophole allows an attacker to connect to any TCP/IP port
on
the client's machine.

A less serious hole has also been found in Netscape Navigator V3.0. This
permits an attacker to discover the client's hostname and IP address
despite
firewalls or even anonymizers.

A.L. Digital notified Microsoft and Netscape of these problems as soon
as they
were discovered, in January, and delayed public release to allow them to
work
around the problems.

A.L. Digital is a high-tech consultancy, specialising in Internet and
security
matters.
