openSUSE Security Update : the Linux Kernel (openSUSE-2016-256)

Medium Nessus Plugin ID 88927

Synopsis

The remote openSUSE host is missing a security update.

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).

Solution

Update the affected the Linux Kernel packages.
