"Updated Samba packages that fix a security vulnerability are now
available.

Samba provides file and printer sharing services to SMB/CIFS clients.

The Samba team discovered an issue that affects version 3.0.0 and
3.0.1 of Samba. If an account for a user is created, but marked as
disabled using the mksmbpasswd script, it is possible for Samba to
overwrite the user's password with the contents of an uninitialized
buffer. This might lead to a disabled account becoming enabled with a
password that could be guessed by an attacker.

Although this is likely to be a low risk issue for most Samba users,
we have provided updated packages, which contain a backported patch
correcting this issue.

Red Hat would like to thank the Samba team for reporting this issue
and providing us with a patch.

Note: Due to a packaging error in samba-3.0.0-14.3E, the winbind
daemon is not automatically restarted when the Samba package is
upgraded. After up2date has installed the samba-3.0.2-4.3E packages,
you must run '/sbin/service winbind condrestart' as root to restart
the winbind daemon."
