ubuntu
Calendar Grey June 29, 2017
Dist Ubuntu Esm H88
Multiple security flaws addressed in the Linux kernel for Ubuntu 20.04 LTS to improve system stability.
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:

USN 3335-1 fixed a vulnerability in the Linux kernel. However, that

fix introduced regressions for some Java applications. This update

addresses the issue. We apologize for the inconvenience.

It was discovered that a use-after-free vulnerability in the core voltage

regulator driver of the Linux kernel. A local attacker could use this to

cause a denial of service or possibly execute arbitrary code.

(CVE-2014-9940)

It was discovered that a buffer overflow existed in the trace subsystem in

the Linux kernel. A privileged local attacker could use this to execute

arbitrary code. (CVE-2017-0605)

Roee Hay discovered that the parallel port printer driver in the Linux

kernel did not properly bounds check passed arguments. A local attacker

with write access to the kernel command line arguments could use this to

execute arbitrary code. (CVE-2017-1000363)

Li Qiang discovered that ...

Update Instructions

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

Ubuntu 14.04 LTS:
  linux-image-3.13.0-123-generic  3.13.0-123.172
  linux-image-3.13.0-123-generic-lpae  3.13.0-123.172
  linux-image-3.13.0-123-lowlatency  3.13.0-123.172
  linux-image-3.13.0-123-powerpc-e500  3.13.0-123.172
  linux-image-3.13.0-123-powerpc-e500mc  3.13.0-123.172
  linux-image-3.13.0-123-powerpc-smp  3.13.0-123.172
  linux-image-3.13.0-123-powerpc64-emb  3.13.0-123.172
  linux-image-3.13.0-123-powerpc64-smp  3.13.0-123.172
  linux-image-generic             3.13.0.123.133
  linux-image-generic-lpae        3.13.0.123.133
  linux-image-lowlatency          3.13.0.123.133
  linux-image-powerpc-e500        3.13.0.123.133
  linux-image-powerpc-e500mc      3.13.0.123.133
  linux-image-powerpc-smp         3.13.0.123.133
  linux-image-powerpc64-emb       3.13.0.123.133
  linux-image-powerpc64-smp       3.13.0.123.133

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.
