1. Topic:

New Netscape packages are available to fix a serious security
problem with Java. It is recommended that all netscape users
update to the new packages. Users of Red Hat Linux 6.0 and 6.1
should use the packages for Red Hat Linux 6.2.

Packages will be made available for Red Hat Linux 5.2 when
fixed binaries are available from Netscape.

2. Relevant releases/architectures:

Red Hat Linux 6.2 - i386, alpha

3. Problem description:

Due to a problem in the Java environment shipped with Netscape,
it would be possible for a java applet on a remote site to
view files on a local machine, and then provide access to those
files for other machines.
