Scroller Ubuntu
Upgrade your Ubuntu installation to resolve the kernel-snapdragon vulnerability leading to system instability and possible security breaches.
The system could be made to crash under certain conditions.

Summary

The system could be made to crash under certain conditions.

Software Description:

- linux-snapdragon: Linux kernel for Snapdragon Processors

Details:

Jann Horn discovered that eCryptfs improperly attempted to use the mmap()

handler of a lower filesystem that did not implement one, causing a

recursive page fault to occur. A local unprivileged attacker could use 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 versions:

Ubuntu 16.04 LTS:
  linux-image-4.4.0-1015-snapdragon  4.4.0-1015.18

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.
