Red Hat, Inc. Security Advisory
Synopsis: New majordomo packages available
Advisory ID: RHSA-2000:005-05
Issue date: 2000-01-20
Updated on: 2000-05-31
Product: Red Hat Powertools
Keywords: majordomo
Cross references: N/A
---------------------------------------------------------------------
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):
N/A
6. RPMs required:
Red Hat Powertools 6.1:
intel:
ftp://ftp.redhat.com/redhat/updates/powertools/6.1/i386/majordomo-1.94.5-2.i386.rpm

7. Verification:

These packages are GPG signed by Red Hat, Inc. for security. Our key
is available at:
http://www.redhat.com/corp/contact.html
You can verify each package with the following command:
rpm --checksig <filename>
If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
rpm --checksig --nogpg <filename>
