DESCRIPTION:
Fedora has issued an update for dracut and udev. This fixes a
vulnerability, which can be exploited by malicious users to disclose
sensitive information.

The vulnerability is caused due to insecure permissions being
assigned to the "/dev/systty" device file. This can be exploited to
monitor the terminal of a user logged in via tty0.

SOLUTION:
Apply updated packages via the yum utility ("yum update dracut
udev").
