DSA-3581 libndp – security update

Julien Bernard discovered that libndp, a library for the IPv6 Neighbor
Discovery Protocol, does not properly perform input and origin checks
during the reception of a NDP message. An attacker in a non-local
network could use this flaw to advertise a node as a router, and cause a
denial of service attack, or act as a man-in-the-middle.

USN-2975-1: Linux kernel vulnerability

Ubuntu Security Notice USN-2975-1

16th May, 2016

linux vulnerability

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

  • Ubuntu 14.04 LTS

Summary

The system could be made to crash or run programs as an administrator.

Software description

  • linux
    – Linux kernel

Details

Philip Pettersson discovered that the Linux kernel’s ASN.1 DER decoder did
not properly process certificate files with tags of indefinite length. A
local unprivileged attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code with administrative
privileges. (CVE-2016-0758)

Update instructions

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

Ubuntu 14.04 LTS:
linux-image-3.13.0-86-powerpc64-emb

3.13.0-86.131
linux-image-3.13.0-86-generic-lpae

3.13.0-86.131
linux-image-3.13.0-86-powerpc-e500mc

3.13.0-86.131
linux-image-3.13.0-86-lowlatency

3.13.0-86.131
linux-image-3.13.0-86-powerpc64-smp

3.13.0-86.131
linux-image-3.13.0-86-generic

3.13.0-86.131
linux-image-3.13.0-86-powerpc-smp

3.13.0-86.131
linux-image-3.13.0-86-powerpc-e500

3.13.0-86.131

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.
