Ubuntu 14.04 LTS USN-3754-1 Critical: Kernel Denial Of Service Risks

ubuntu
Calendar Grey August 24, 2018
Dist Ubuntu Esm H88
Ubuntu 3754-2 addresses numerous kernel security flaws that could lead to potential system failures and information breaches.
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:

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 an information disclosure vulnerability existed in

the ACPI implementation of the Linux kernel. A local attacker could use

this to expose sensitive information (kernel memory addresses).

(CVE-2017-11472)

It was discovered that a buffer overflow existed in the ACPI table parsing

implementation in the Linux kernel. A local attacker could use this to

construct a malicious ACPI table that, when loaded, caused a denial of

service (system crash) or possibly execute arbitrary code.

(CVE-2017-11473)

It was discovered that the generic SCSI driver in the Linux kernel did...

Update Instructions

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

Ubuntu 14.04 LTS:
  linux-image-3.13.0-157-generic  3.13.0-157.207
  linux-image-3.13.0-157-generic-lpae  3.13.0-157.207
  linux-image-3.13.0-157-lowlatency  3.13.0-157.207
  linux-image-3.13.0-157-powerpc-e500  3.13.0-157.207
  linux-image-3.13.0-157-powerpc-e500mc  3.13.0-157.207
  linux-image-3.13.0-157-powerpc-smp  3.13.0-157.207
  linux-image-3.13.0-157-powerpc64-emb  3.13.0-157.207
  linux-image-3.13.0-157-powerpc64-smp  3.13.0-157.207
  linux-image-generic             3.13.0.157.167
  linux-image-generic-lpae        3.13.0.157.167
  linux-image-lowlatency          3.13.0.157.167
  linux-image-powerpc-e500        3.13.0.157.167
  linux-image-powerpc-e500mc      3.13.0.157.167
  linux-image-powerpc-smp         3.13.0.157.167
  linux-image-powerpc64-emb       3.13.0.157.167
  linux-image-powerpc64-smp       3.13.0.157.167

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.
