1. Topic:

New majordomo packages are available to fix local security problems in majordomo.

2. Relevant releases/architectures:

Red Hat Powertools 6.1 - i386 alpha sparc

3. Problem description:

A vulnerability in /usr/lib/majordomo/resend and /usr/lib/majordomo/wrapper will allow execution of arbitrary commands with elevated privileges.

It is recommended that all users of Red Hat Linux using the majordomo package upgrade to the fixed package, which will resolve the vulnerability in /usr/lib/majordomo/resend.  To secure /usr/lib/majodomo/wrapper, please read the solution section below.

Once an official patch has been released by the majordomo maintainers, we will release an updated package which will fix both vulnerabilities.

4. Solution:

For each RPM for your particular architecture, run:

rpm -Fvh [filename]

where filename is the name of the RPM.

Once the package is installed, become "root" and execute this command:

chmod o-x /usr/lib/majordomo/wrapper

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