Ubuntu 17.04: USN-3345-1 Moderate: Kernel Denial of Service Issues

Dist Ubuntu Esm H88
Several security flaws in the Linux kernel for Ubuntu have been addressed in USN-3345-1. Make sure to perform an update on your machine.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux: Linux kernel

- linux-raspi2: Linux kernel for Raspberry Pi 2

Details:

USN 3324-1 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.

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)

It was discovered that a double-free vulnerability existed in the IPv4

stack of the Linux kernel. An attacker could use this to cause a denial of

service (system crash). (CVE-2017-8890)

Andrey Konovalov discovered an IPv6 out-of-bounds read error in the Linux

kernel's IPv6 stack. A local attacker could cause a denial of service or

potentially other unspecified problems. (CVE-2017...

Update Instructions

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

Ubuntu 17.04:
  linux-image-4.10.0-1010-raspi2  4.10.0-1010.13
  linux-image-4.10.0-26-generic   4.10.0-26.30
  linux-image-4.10.0-26-generic-lpae  4.10.0-26.30
  linux-image-4.10.0-26-lowlatency  4.10.0-26.30
  linux-image-generic             4.10.0.26.28
  linux-image-generic-lpae        4.10.0.26.28
  linux-image-lowlatency          4.10.0.26.28
  linux-image-raspi2              4.10.0.1010.12

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.
