Users with Oracle Linux Premier Support can now use Ksplice to patch
against this Security Advisory.

We recommend that all users of  Oracle Linux 5 install these updates.

Users of Ksplice Uptrack can install these updates by running :

# /usr/sbin/uptrack-upgrade -y
On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any additional action.

Description of changes:

* CVE-2011-4086: Denial of service in journaling block device.

The journal block device assumed that a buffer marked as unwritten
or delay could be live without checking if the buffer was mapped.

An unprivileged local user could use this flaw to crash the system.
