Dist Ubuntu Esm H88
Tackling vital concerns within Ubuntu 12.04's system architecture, focusing on vulnerabilities and essential patches for user installations.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

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

Details:

USN-3933-1 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.

It was discovered that an information leak vulnerability existed in the

Bluetooth implementation of the Linux kernel. An attacker within Bluetooth

range could possibly expose sensitive information (kernel memory).

(CVE-2017-1000410)

It was discovered that the USB serial device driver in the Linux kernel did

not properly validate baud rate settings when debugging is enabled. A local

attacker could use this to cause a denial of service (system crash).

(CVE-2017-18360)

Mathias Payer and Hui Peng discovered a use-after-free vulnerability in the

Advanced Linux Sound Architecture (ALSA) subsystem. A physical...

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 ESM:
  linux-image-3.13.0-168-generic  3.13.0-168.218~precise1
  linux-image-3.13.0-168-generic-lpae  3.13.0-168.218~precise1
  linux-image-3.13.0-168-lowlatency  3.13.0-168.218~precise1
  linux-image-generic-lpae-lts-trusty  3.13.0.168.157
  linux-image-generic-lts-trusty  3.13.0.168.157

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
