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: http://ift.tt/17VXqjU.
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.
