Fedora Update Notification

Name        : udev
Product     : Fedora 13
Version     : 153
Release     : 5.fc13
URL         : http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev.html
Summary     : A userspace implementation of devfs
Description :
The udev package contains an implementation of devfs in
userspace using sysfs and netlink.

Update Information:

It was discovered that /dev/systty device file created by dracut-generated initramfs scripts used an insecure file permissions.  This could possibly allow local user to snoop on other user's terminal.

Updated dracut no longer creates this file as device file, rather creates it a symbolic link to tty0 device file.  However, for this change to take effect, user needs to re-generate initramfs (any initramfs for all kernels that are going to be booted in the future) using updated dracut version and reboot the system.

On Fedora 13, dracut update addressing this flaw was previously released as bug fix update.  This update only provides updated udev packages that replace systty device file with a symlink on udev package upgrade and each udev start.  This provides a work-around fix for users that fail to regenerate their initramfs and reboot as described above.
