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.


* CVE-2013-4345: Off-by-one in the ANSI Crypto RNG.

An off-by-one flaw was found in the way the ANSI CPRNG implementation in
the Linux kernel processed non-block size aligned requests. This could lead
to random numbers being generated with less bits of entropy than expected
when ANSI CPRNG was used.


* CVE-2013-0343: Denial of service in IPv6 privacy extensions.

A malicious remote user can disable IPv6 privacy extensions by flooding the host
with malicious temporary addresses.
