Ubuntu Security Notice USN-7298-1

linux, linux-lts-xenial vulnerability

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

=2D Ubuntu 16.04 LTS
=2D Ubuntu 14.04 LTS

Summary:

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

Software Description:
=2D linux: Linux kernel
=2D linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trus=
ty

Details:

Attila Sz=C3=A1sz discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.

Update instructions:

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

Ubuntu 16.04 LTS
  linux-image-4.4.0-264-generic   4.4.0-264.298
                                  Available with Ubuntu Pro
  linux-image-4.4.0-264-lowlatency  4.4.0-264.298
                                  Available with Ubuntu Pro
  linux-image-generic             4.4.0.264.270
                                  Available with Ubuntu Pro
  linux-image-generic-lts-xenial  4.4.0.264.270
                                  Available with Ubuntu Pro
  linux-image-lowlatency          4.4.0.264.270
                                  Available with Ubuntu Pro
  linux-image-virtual             4.4.0.264.270
                                  Available with Ubuntu Pro

Ubuntu 14.04 LTS
  linux-image-4.4.0-264-generic   4.4.0-264.298~14.04.1
                                  Available with Ubuntu Pro
  linux-image-4.4.0-264-lowlatency  4.4.0-264.298~14.04.1
                                  Available with Ubuntu Pro

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.
