ubuntu
Calendar Grey April 2, 2019
Dist Ubuntu Esm H88
Numerous vulnerabilities addressed in Ubuntu 14.04 LTS Linux core impacting system performance and data security.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux: Linux kernel

Details:

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 physically proximate

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

(CVE-2018-19824)

Shlomi Oberman, Yuli Shapiro, and Ran Menscher discovered an information

leak in the Bluetooth implementation of the Linux kernel. An attacker

within Bluetooth range could u...

Update Instructions

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

Ubuntu 14.04 LTS:
  linux-image-3.13.0-168-generic  3.13.0-168.218
  linux-image-3.13.0-168-generic-lpae  3.13.0-168.218
  linux-image-3.13.0-168-lowlatency  3.13.0-168.218
  linux-image-3.13.0-168-powerpc-e500  3.13.0-168.218
  linux-image-3.13.0-168-powerpc-e500mc  3.13.0-168.218
  linux-image-3.13.0-168-powerpc-smp  3.13.0-168.218
  linux-image-3.13.0-168-powerpc64-emb  3.13.0-168.218
  linux-image-3.13.0-168-powerpc64-smp  3.13.0-168.218
  linux-image-generic             3.13.0.168.179
  linux-image-generic-lpae        3.13.0.168.179
  linux-image-lowlatency          3.13.0.168.179
  linux-image-powerpc-e500        3.13.0.168.179
  linux-image-powerpc-e500mc      3.13.0.168.179
  linux-image-powerpc-smp         3.13.0.168.179
  linux-image-powerpc64-emb       3.13.0.168.179
  linux-image-powerpc64-smp       3.13.0.168.179
  linux-image-virtual             3.13.0.168.179

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.
