1. Topic:

A security bug has been discovered and fixed in the userhelper program.

2000-01-04: SysVinit package added for Red Hat Linux 6.0 to fix
            a dependency problem.

2. Relevant releases/architectures:

Red Hat Linux 6.0 and 6.1, all architectures.

3. Problem description:

A security bug was found in userhelper; the bug can be exploited to
provide local users with root access.

The bug has been fixed in userhelper-1.17, and pam-0.68-10 has been
modified to help prevent similar attacks on other software in the future.

2000-01-04: Red Hat Linux 6.0 users will need to upgrade to
            SysVinit-2.77-2 to fix a minor dependency issue.

4. Solution:

For each RPM for your particular architecture, run:
    rpm -Uvh <filename>
where filename is the name of the RPM.

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla/ for more info):
