Ubuntu Security Notice USN-3290-1
May 17, 2017

linux vulnerability

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

- Ubuntu 14.04 LTS


The system could be made to crash under certain conditions.

Software Description:
- linux: Linux kernel


Marco Grassi discovered that the TCP implementation in the Linux kernel
mishandles socket buffer (skb) truncation. A local attacker could use this
to cause a denial of service (system crash).

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-3.13.0-119-generic 3.13.0-119.166
linux-image-3.13.0-119-generic-lpae 3.13.0-119.166
linux-image-3.13.0-119-lowlatency 3.13.0-119.166
linux-image-3.13.0-119-powerpc-e500 3.13.0-119.166
linux-image-3.13.0-119-powerpc-e500mc 3.13.0-119.166
linux-image-3.13.0-119-powerpc-smp 3.13.0-119.166
linux-image-3.13.0-119-powerpc64-smp 3.13.0-119.166

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.
