Releases

• Ubuntu 12.04

Packages

• linux-lts-trusty - Linux hardware enablement kernel from Trusty for Precise ESM

Details

USN-3822-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu
12.04 ESM.

Jim Mattson discovered that the KVM implementation in the Linux kernel
mismanages the #BP and #OF exceptions. A local attacker in a guest virtual
machine could use this to cause a denial of service (guest OS crash).
(CVE-2016-9588)

It was discovered that the generic SCSI driver in the Linux kernel did not
properly enforce permissions on kernel memory access. A local attacker
could use this to expose sensitive information or possibly elevate
privileges. (CVE-2017-13168)

Andrey Konovalov discovered that the CDC USB Ethernet driver did not
properly validate device descriptors. A physically proximate attacker could
use this to cause a denial of service (system crash). (CVE-2017-16649)

It was discovered that an integer overflow existed in the CD-ROM driver of
the Linux kernel. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2018-16658)

It was discovered that an integer overflow existed in the HID Bluetooth
implementation in the Linux kernel that could lead to a buffer overwrite.
An attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2018-9363)
