Fedora Legacy Update Advisory

Synopsis: Updated util-linux resolves security vulnerability
Advisory ID: FLSA:1256
Issue date: 2004-03-04
Product: Red Hat Linux
Keywords: Security
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=1256
CVE Names: CAN-2004-0080
------------------------------------------------------------------------


----------------------------------------------------------------------
1. Topic:

Updated util-linux packages that fix an information leak in the login program are now available.

2. Relevent releases/architectures:

Red Hat Linux 7.2 - i386

3. Problem description:
The util-linux package contains a large variety of low-level system utilities that are necessary for a Linux system to function.

In some situations, the login program could use a pointer that had been freed and reallocated. This could cause unintentional data leakage.

Note: Red Hat Linux releases newer than 7.2 are not vulnerable to this issue. It is recommended that all users upgrade to these updated packages, which are not vulnerable to this issue.



Fedora Legacy would like to thank Matthew Lee of Fleming College for finding and reporting this issue, and Jesse Keating for providing a backported patch for Red Hat Linux 7.2.

4. 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 yum and apt. Many people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content.

These packages are GPG signed by Fedora Legacy for security. Our key is available from http://www.fedoralegacy.org/about/security.php

You can verify each package with the following command:

rpm --checksig -v

If you only wish to verify that each package has not been corrupted or tampered with, examine only the sha1sum with the following command:

sha1sum
