"This update fixes the CVEs described below.

CVE-2015-7566

Ralf Spenneberg of OpenSource Security reported that the visor driver
crashes when a specially crafted USB device without bulk-out endpoint
is detected.

CVE-2015-8767

An SCTP denial of service was discovered which can be triggered by a
local attacker during a heartbeat timeout event after the 4-way
handshake.

CVE-2015-8785

It was discovered that local users permitted to write to a file on a
FUSE filesystem could cause a denial of service (unkillable loop in
the kernel).

CVE-2016-0723

A use-after-free vulnerability was discovered in the TIOCGETD ioctl. A
local attacker could use this flaw for denial of service.

CVE-2016-2069

Andy Lutomirski discovered a race condition in flushing of the TLB
when switching tasks. On an SMP system this could possibly lead to a
crash, information leak or privilege escalation.

For the oldoldstable distribution (squeeze), these problems have been
fixed in version 2.6.32-48squeeze19. Additionally, this version
includes upstream stable update 2.6.32.70. This is the final update to
the linux-2.6 package for squeeze.

For the oldstable distribution (wheezy), these problems will be fixed
soon.

For the stable distribution (jessie), CVE-2015-7566, CVE-2015-8767 and
CVE-2016-0723 were fixed in linux version 3.16.7-ckt20-1+deb8u3 and
the remaining problems will be fixed soon.

to automatically clean and format it as much as possible without
