--------------------------------------------------------------------- Fedora Legacy Update Advisory
Synopsis: Updated udev packages fix a security issue Advisory ID: FLSA:175818 Issue date: 2006-02-27 Product: Fedora Core Keywords: Bugfix CVE Names: CVE-2005-3631 ---------------------------------------------------------------------
--------------------------------------------------------------------- 1. Topic:
Updated udev packages that fix a security issue are now available.
The udev package contains an implementation of devfs in userspace using sysfs and /sbin/hotplug.
2. Relevant releases/architectures:
Fedora Core 2 - i386 Fedora Core 3 - i386, x86_64
3. Problem description:
Richard Cunningham discovered a flaw in the way udev sets permissions on various files in /dev/input. It may be possible for an authenticated attacker to gather sensitive data entered by a user at the console, such as passwords. The Common Vulnerabilities and Exposures project has assigned the name CVE-2005-3631 to this issue.
All users of udev should upgrade to these updated packages, which contain a backported patch and are not vulnerable to this issue.
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. Please visit http://www.fedoralegacy.org/docs for directions on how to configure yum and apt-get.
5. Bug IDs fixed:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=175818
6. RPMs required:
Fedora Core 2:
SRPM: udev-024-6.2.legacy.src.rpm
i386: udev-024-6.2.legacy.i386.rpm
Fedora Core 3:
SRPM: udev-039-10.FC3.9.legacy.src.rpm
i386: udev-039-10.FC3.9.legacy.i386.rpm
x86_64: udev-039-10.FC3.9.legacy.x86_64.rpm
7. Verification:
SHA1 sum Package Name ---------------------------------------------------------------------

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 <filename>
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 <filename>
