   openSUSE Security Update: Security update for the Linux Kernel
______________________________________________________________________________

Announcement ID: openSUSE-SU-2016:0537-1
Rating: important
References: #907378 #961500 #963767 #965308 #965356
Cross-References: CVE-2016-0723 CVE-2016-2069
Affected Products:
openSUSE 13.2
______________________________________________________________________________

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).
