USN-3384-1: Linux kernel vulnerabilities

Ubuntu Security Notice USN-3384-1

10th August, 2017

linux, linux-raspi2 vulnerabilities

A security issue affects these releases of Ubuntu and its
derivatives:

  • Ubuntu 17.04

Summary

Several security issues were fixed in the Linux kernel.

Software description

  • linux
    – Linux kernel

  • linux-raspi2
    – Linux kernel for Raspberry Pi 2

Details

Andrey Konovalov discovered a race condition in the UDP Fragmentation
Offload (UFO) code in the Linux kernel. A local attacker could use this to
cause a denial of service or execute arbitrary code. (CVE-2017-1000112)

Andrey Konovalov discovered a race condition in AF_PACKET socket option
handling code in the Linux kernel. A local unprivileged attacker could use
this to cause a denial of service or possibly execute arbitrary code.
(CVE-2017-1000111)

Update instructions

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

Ubuntu 17.04:
linux-image-4.10.0-32-generic-lpae

4.10.0-32.36
linux-image-generic 4.10.0.32.32
linux-image-generic-lpae 4.10.0.32.32
linux-image-4.10.0-32-generic

4.10.0-32.36
linux-image-4.10.0-1015-raspi2

4.10.0-1015.18
linux-image-4.10.0-32-lowlatency

4.10.0-32.36
linux-image-lowlatency 4.10.0.32.32
linux-image-raspi2 4.10.0.1015.16

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

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.
