openSUSE Security Update : the Linux Kernel (openSUSE-2017-716) (Stack Clash)

This script is Copyright (C) 2017 Tenable Network Security, Inc.

Synopsis :

The remote openSUSE host is missing a security update.

Description :

The openSUSE Leap 42.2 kernel was updated to 4.4.72 to receive various
security and bugfixes.

The following security bugs were fixed :

- CVE-2017-1000364: An issue was discovered in the size of
the stack guard page on Linux, specifically a 4k stack
guard page is not sufficiently large and can be 'jumped'
over (the stack guard page is bypassed), this affects
Linux Kernel versions 4.11.5 and earlier (the stackguard
page was introduced in 2010) (bnc#1039348).

- CVE-2017-1000380: sound/core/timer.c in the Linux kernel
is vulnerable to a data race in the ALSA /dev/snd/timer
driver resulting in local users being able to read
information belonging to other users, i.e.,
uninitialized memory contents may be disclosed when a
read and an ioctl happen at the same time (bnc#1044125).

- CVE-2017-7346: The vmw_gb_surface_define_ioctl function
in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux
kernel did not validate certain levels data, which
allowed local users to cause a denial of service (system
hang) via a crafted ioctl call for a /dev/dri/renderD*
device (bnc#1031796).

- CVE-2017-9242: The __ip6_append_data function in
net/ipv6/ip6_output.c in the Linux kernel is too late in
checking whether an overwrite of an skb data structure
may occur, which allowed local users to cause a denial
of service (system crash) via crafted system calls
