linux-lts-xenial - Linux hardware enablement kernel from Xenial for Trusty

Details

USN-3234-1 fixed vulnerabilities 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.

Ralf Spenneberg discovered that the ext4 implementation in the Linux kernel
did not properly validate meta block groups. An attacker with physical
access could use this to specially craft an ext4 image that causes a denial
of service (system crash). (CVE-2016-10208)

It was discovered that the Linux kernel did not clear the setgid bit during
a setxattr call on a tmpfs filesystem. A local attacker could use this to
gain elevated group privileges. (CVE-2017-5551)
