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

high Nessus Plugin ID 88927
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
