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

high Nessus Plugin ID 101127



The remote openSUSE host is missing a security update.


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).
