CVE-2015-2925

Jann Horn discovered that when a subdirectory of a filesystem was
bind-mounted into a chroot or mount namespace, a user that should be
confined to that chroot or namespace could access the whole of that
filesystem if they had write permission on an ancestor of the
subdirectory. This is not a common configuration for this kernel
version.

CVE-2015-5257

Moein Ghasemzadeh of Istuary Innovation Labs reported that a USB
device could cause a denial of service (crash) by imitating a
Whiteheat USB serial device but presenting a smaller number of
endpoints.

CVE-2015-7613

Dmitry Vyukov discovered that System V IPC objects (message queues and
shared memory segments) were made accessible before their ownership
and other attributes were fully initialised. If a local user can race
against another user or service creating a new IPC object, this may
result in unauthorised information disclosure, unauthorised
information modification, denial of service and/or privilege
escalation.

A similar issue existed with System V semaphore arrays, but
was less severe because they were always cleared before
being fully initialised.

For the oldoldstable distribution (squeeze), these problems have been
fixed in version 2.6.32-48squeeze16.

For the oldstable distribution (wheezy), these problems will be fixed
in version 3.2.68-1+deb7u5.

For the stable distribution (jessie), these problems will be fixed in
version 3.16.7-ckt11-1+deb8u5 or have been fixed 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."
