RHSA-2005:864 - Security Advisory

Topic

Updated udev packages that fix a security issue are now available.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

Description

The udev package contains an implementation of devfs in userspace using
sysfs and /sbin/hotplug.

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.
