Affected Products:
openSUSE Leap 42.2
______________________________________________________________________________

An update that solves four vulnerabilities and has 35 fixes
is now available.

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 (bnc#1041431).
