Fedora 14 : dracut-006-5.fc14 / udev-161-7.fc14 (2010-17930)
Medium Nessus Plugin ID 50814
SynopsisThe remote Fedora host is missing one or more security updates.
DescriptionIt 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.
This update also 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.
SolutionUpdate the affected dracut and / or udev packages.
