Ubuntu Security Notice USN-3364-1
July 24, 2017

linux, linux-raspi2, linux-snapdragon vulnerabilities
==========================================================================

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

– Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
– linux: Linux kernel
– linux-raspi2: Linux kernel for Raspberry Pi 2
– linux-snapdragon: Linux kernel for Snapdragon processors

Details:

It was discovered that the Linux kernel did not properly initialize a Wake-
on-Lan data structure. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2014-9900)

It was discovered that the Linux kernel did not properly restrict access to
/proc/iomem. A local attacker could use this to expose sensitive
information. (CVE-2015-8944)

Alexander Potapenko discovered a race condition in the Advanced Linux Sound
Architecture (ALSA) subsystem in the Linux kernel. A local attacker could
use this to expose sensitive information (kernel memory).
(CVE-2017-1000380)

Li Qiang discovered that the DRM driver for VMware Virtual GPUs in the
Linux kernel did not properly validate some ioctl arguments. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2017-7346)

Jann Horn discovered that bpf in Linux kernel does not restrict the output
of the print_bpf_insn function. A local attacker could use this to obtain
sensitive address information. (CVE-2017-9150)

Murray McAllister discovered that the DRM driver for VMware Virtual GPUs in
the Linux kernel did not properly initialize memory. A local attacker could
use this to expose sensitive information (kernel memory). (CVE-2017-9605)

Update instructions:

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

Ubuntu 16.04 LTS:
linux-image-4.4.0-1065-raspi2 4.4.0-1065.73
linux-image-4.4.0-1067-snapdragon 4.4.0-1067.72
linux-image-4.4.0-87-generic 4.4.0-87.110
linux-image-4.4.0-87-generic-lpae 4.4.0-87.110
linux-image-4.4.0-87-lowlatency 4.4.0-87.110
linux-image-4.4.0-87-powerpc-e500mc 4.4.0-87.110
linux-image-4.4.0-87-powerpc-smp 4.4.0-87.110
linux-image-4.4.0-87-powerpc64-emb 4.4.0-87.110
linux-image-4.4.0-87-powerpc64-smp 4.4.0-87.110
linux-image-generic 4.4.0.87.93
linux-image-generic-lpae 4.4.0.87.93
linux-image-lowlatency 4.4.0.87.93
linux-image-powerpc-e500mc 4.4.0.87.93
linux-image-powerpc-smp 4.4.0.87.93
linux-image-powerpc64-emb 4.4.0.87.93
linux-image-powerpc64-smp 4.4.0.87.93
linux-image-raspi2 4.4.0.1065.66
linux-image-snapdragon 4.4.0.1067.60

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.
