--------------------------------------------------------------------- Red Hat, Inc. Security Advisory
Synopsis: new modutils release addresses more local root compromise possibilities Advisory ID: RHSA-2000:108-05 Issue date: 2000-11-16 Updated on: 2000-11-27 Product: Red Hat Linux Keywords: modutils root exploit security Cross references: N/A ---------------------------------------------------------------------
1. Topic:
A new modutils-2.3.21 package has been released to correctly enable safe
guard measures introduced in modutils-2.3.20.
2000-11-27: Added packages for Red Hat Linux 7 for Alpha
2. Relevant releases/architectures:
Red Hat Linux 6.2 - i386, alpha, sparc Red Hat Linux 7.0 - i386, alpha
3. Problem description:
The previous packages of modutils released to address a local root
compromise contained an error in new safe guards that caused them to
not properly be enabled when run as root from the kmod process. These
new safe guards check the arguments passed to modules. The new 2.3.21
modutils package fixes this error and correctly checks the arguments
when running from kmod, limiting kernel module arguments to those
specified in /etc/conf.modules (on Red Hat Linux 6.2) or /etc/modules.conf
(on Red Hat Linux 7). This release supersedes the previous modutils errata
packages.
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
modutils-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):
20749 - local root exploit via modutils

7. Verification:
MD5 sum Package Name -------------------------------------------------------------------------- b21fb3e4bdef79b28c3cfbd679fa9543 6.2/SRPMS/modutils-2.3.21-0.6.2.src.rpm 73953a51d51d173b8acbf93ef387fd81 6.2/alpha/modutils-2.3.21-0.6.2.alpha.rpm 4439637a314f3bb60970795d614022b1 6.2/i386/modutils-2.3.21-0.6.2.i386.rpm c063d22e0aeeaa762e5bd9903af42cc3 6.2/sparc/modutils-2.3.21-0.6.2.sparc.rpm 3ae5ad039cb895f0599d4d52ccf61275 7.0/SRPMS/modutils-2.3.21-1.src.rpm 6f68c415e4ec7f18bc68e987e488056b 7.0/alpha/modutils-2.3.21-1.alpha.rpm 46b7f3331bccd927d9d7fefbec74f721 7.0/i386/modutils-2.3.21-1.i386.rpm
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>
