Fedora 13 : udev-153-5.fc13 (2010-17912)

Synopsis :

The remote Fedora host is missing a security update.

Description :

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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
