linux-lts-xenial regression

USN-3392-1 fixed a regression in the Linux kernel for Ubuntu 16.04 LTS.
This update provides the corresponding updates for the Linux Hardware
Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS.

USN-3378-2 fixed vulnerabilities in the Linux Hardware Enablement
kernel. Unfortunately, a regression was introduced that prevented
conntrack from working correctly in some situations. This update
fixes the problem.

We apologize for the inconvenience.

Original advisory details:

Fan Wu and Shixiong Zhao discovered a race condition between inotify events
and vfs rename operations in the Linux kernel. An unprivileged local
attacker could use this to cause a denial of service (system crash) or
execute arbitrary code. (CVE-2017-7533)

It was discovered that the Linux kernel did not properly restrict
RLIMIT_STACK size. A local attacker could use this in conjunction with
another vulnerability to possibly execute arbitrary code.
(CVE-2017-1000365)

李强 discovered that the Virtio GPU driver in the Linux kernel did not
properly free memory in some situations. A local attacker could use this to
cause a denial of service (memory consumption). (CVE-2017-10810)

石磊 discovered that the RxRPC Kerberos 5 ticket handling code in the
Linux kernel did not properly verify metadata. A remote attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2017-7482)
