USN-2977-1: Linux kernel (Vivid HWE) vulnerability

Ubuntu Security Notice USN-2977-1

16th May, 2016

linux-lts-vivid vulnerability

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

Summary

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

Software description

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.

Update instructions

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

Ubuntu 14.04 LTS:
linux-image-3.19.0-59-powerpc64-smp

3.19.0-59.66~14.04.1
linux-image-3.19.0-59-lowlatency

3.19.0-59.66~14.04.1
linux-image-3.19.0-59-powerpc64-emb

3.19.0-59.66~14.04.1
linux-image-3.19.0-59-powerpc-smp

3.19.0-59.66~14.04.1
linux-image-3.19.0-59-powerpc-e500mc

3.19.0-59.66~14.04.1
linux-image-3.19.0-59-generic-lpae

3.19.0-59.66~14.04.1
linux-image-3.19.0-59-generic

3.19.0-59.66~14.04.1

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-vivid, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
