Users with Oracle Linux Premier Support can now use Ksplice to patch

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

* CVE-2013-4162: Denial-of-service with IPv6 sockets with UDP_CORK.

When pushing pending frames in IPv6 udp code, an incorrect function call can
be made. This allows local users to cause a denial of service (BUG and system
crash) via a crafted application that uses the UDP_CORK option in a
setsockopt system call.

* CVE-2013-4299: Information leak in device mapper persistent snapshots.

An information leak flaw was found in the way Linux kernel's device
mapper subsystem, under certain conditions, interpreted data written to
snapshot block devices. An attacker could use this flaw to read data
from disk blocks in free space, which are normally inaccessible.
