"This update fixes the CVEs described below.

CVE-2015-7550

Dmitry Vyukov discovered a race condition in the keyring subsystem
that allows a local user to cause a denial of service (crash).

CVE-2015-8543

It was discovered that a local user permitted to create raw sockets
could cause a denial of service by specifying an invalid protocol
number for the socket. The attacker must have the CAP_NET_RAW
capability.

CVE-2015-8575

David Miller discovered a flaw in the Bluetooth SCO sockets
implementation that leads to an information leak to local users.

In addition, this update fixes a regression in the previous update :

#808293

A regression in the UDP implementation prevented freeradius and some
other applications from receiving data.

For the oldoldstable distribution (squeeze), these problems have been
fixed in version 2.6.32-48squeeze18.

For the oldstable distribution (wheezy), these problems have been
fixed in version 3.2.73-2+deb7u2.

For the stable distribution (jessie), these problems have been fixed
in version 3.16.7-ckt20-1+deb8u2 or earlier.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
