LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu
12.04 ESM.

It was discovered that the Linux kernel did not properly initialize a Wake-
on-Lan data structure. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2014-9900)

It was discovered that the Linux kernel did not properly restrict access to
/proc/iomem. A local attacker could use this to expose sensitive
information. (CVE-2015-8944)

It was discovered that a use-after-free vulnerability existed in the
performance events and counters subsystem of the Linux kernel for ARM64. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2015-8955)

It was discovered that the SCSI generic (sg) driver in the Linux kernel
contained a double-free vulnerability. A local attacker could use this to
cause a denial of service (system crash). (CVE-2015-8962)

Sasha Levin discovered that a race condition existed in the performance
events and counters subsystem of the Linux kernel when handling CPU unplug
events. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2015-8963)

Tilman Schmidt and Sasha Levin discovered a use-after-free condition in the
TTY implementation in the Linux kernel. A local attacker could use this to
expose sensitive information (kernel memory). (CVE-2015-8964)

It was discovered that the fcntl64() system call in the Linux kernel did
not properly set memory limits when returning on 32-bit ARM processors. A
local attacker could use this to gain administrative privileges.
(CVE-2015-8966)

It was discovered that the system call table for ARM 64-bit processors in
the Linux kernel was not write-protected. An attacker could use this in
conjunction with another kernel vulnerability to execute arbitrary code.
(CVE-2015-8967)

It was discovered that the generic SCSI block layer in the Linux kernel did
not properly restrict write operations in certain situations. A local
attacker could use this to cause a denial of service (system crash) or
possibly gain administrative privileges. (CVE-2016-10088)

Alexander Potapenko discovered a race condition in the Advanced Linux Sound
Architecture (ALSA) subsystem in the Linux kernel. A local attacker could
use this to expose sensitive information (kernel memory).
(CVE-2017-1000380)

Li Qiang discovered that the DRM driver for VMware Virtual GPUs in the
Linux kernel did not properly validate some ioctl arguments. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2017-7346)

Tuomas Haanpaa and Ari Kauppi discovered that the NFSv2 and NFSv3 server
implementations in the Linux kernel did not properly check for the end of
buffer. A remote attacker ... [Please see the references for more information on the vulnerabilities]");
