DESCRIPTION

* 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.
