Red Hat 7.1 RHSA-2001:132-03 Critical: Util-linux Credential Escalation

red hat
Calendar Grey October 16, 2001
Dist Redhat Esm H88
Critical fix required for privilege escalation flaw in util-linux login PAM component. Urgent update recommended to safeguard user profiles.
New util-linux packages are available that fix a problem with /bin/login's PAM implementation

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.

Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
