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

Alexander Popov discovered that the N_HDLC line discipline implementation
in the Linux kernel contained a double-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or possibly gain
administrative privileges.

Update instructions

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

Ubuntu 14.04 LTS:

linux-image-powerpc-smp

3.13.0.112.120

linux-image-3.13.0-112-powerpc-e500

3.13.0.112.120

linux-image-powerpc64-smp

3.13.0.112.120

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.

Details

Multiple security issues were discovered in Firefox. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to bypass same origin restrictions, obtain
sensitive information, spoof the addressbar, spoof the print dialog,
cause a denial of service via application crash or hang, or execute
arbitrary code. (CVE-2017-5398, CVE-2017-5399, CVE-2017-5400,
