--------------------------------------------------------------------- Red Hat, Inc. Security Advisory
Synopsis: Updated modutils fixing local root security bug available Advisory ID: RHSA-2000:108-03 Issue date: 2000-11-16 Updated on: 2000-11-17 Product: Red Hat Linux Keywords: modutils root exploit security Cross references: N/A ---------------------------------------------------------------------
1. Topic:
A local root exploit in modutils has been fixed.
2000-11-17: New packages available for Red Hat Linux 6.2 to
fix an error in the previous packages.
2. Relevant releases/architectures:
Red Hat Linux 6.2 - i386, alpha, sparc Red Hat Linux 7.0 - i386
3. Problem description:
modutils, a package that helps the kernel automatically load kernel modules
(device drivers etc.) when they're needed, could be abused to execute code
as root.
modutils versions between 2.3.0 and 2.3.20 are affected.
4. Solution:
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
2000-11-17: For Red Hat Linux 6.2, if you installed the previous
(2.3.20-0.6.2) packages, you will need to run:
mv /etc/modules.conf /etc/conf.modules
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
