* A flaw was found in the way the Linux kernel's TCP/IP protocol suite
implementation handled IPv6 sockets that used the UDP_CORK option. A

data from disk blocks in free space, which are normally inaccessible.
Red Hat would like to thank Hannes Frederic Sowa for reporting
and Fujitsu for reporting CVE-2013-4299.
This update also fixes several bugs. Documentation for these changes
will be available shortly from the Technical Notes document linked to
in the References section.
