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

Description:

   This update for the Linux Kernel 4.4.49-92_14 fixes several issues.

   The following security bugs were fixed:

   - CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in
     the Linux kernel did not properly validate certain block-size data,
     which allowed local users to cause a denial of service (overflow) or
     possibly have unspecified other impact via crafted system calls
     (bsc#1030575, bsc#1031660).
   - CVE-2017-7294: The vmw_surface_define_ioctl function in
     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not
     validate addition of certain levels data, which allowed local users to
     trigger an integer overflow and out-of-bounds write, and cause a denial
     of service (system hang or crash) or possibly gain privileges, via a
     crafted ioctl call for a /dev/dri/renderD* device (bsc#1031440,
     bsc#1031481).
