______________________________________________________________________________

   An update that solves two vulnerabilities and has three
   fixes is now available.

Description:


   The openSUSE 13.2 kernel was updated to receive security and bugfixes.

   It also fixes a regression that caused the Chromium sandbox to no longer
   work (bsc#965356).

   Following security bugs were fixed:
   - CVE-2016-2069: A flaw was discovered in a way the Linux deals with
     paging structures. When Linux invalidates a paging structure that is not
     in use locally, it could, in principle, race against another CPU that is
     switching to a process that uses the paging structure in question,
     causing a local denial service (machine crash). (bnc#963767).
   - CVE-2016-0723: Race condition in the tty_ioctl function in
     drivers/tty/tty_io.c in the Linux kernel allowed local users to obtain
     sensitive information from kernel memory or cause a denial of service
     (use-after-free and system crash) by making a TIOCGETD ioctl call during
     processing of a TIOCSETD ioctl call (bnc#961500).

   The following non-security bugs were fixed:
   - Bluetooth: ath3k: workaround the compatibility issue with xHCI
     controller (bnc#907378).
   - kABI fix for addition of user_namespace.flags field (bnc#965308,
     bnc#965356).
   - userns: Add a knob to disable setgroups on a per user namespace basis
     (bnc#965308, bnc#965356).
   - userns: Allow setting gid_maps without privilege when setgroups is
     disabled (bnc#965308, bnc#965356).
   - userns: Rename id_map_mutex to userns_state_mutex (bnc#965308,
     bnc#965356).
