USN-3404-2: Linux kernel (HWE) vulnerability

Ubuntu security notices - 2017.08.29, k - 02:56
Ubuntu Security Notice USN-3404-2

28th August, 2017

linux-hwe vulnerability

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

  • Ubuntu 16.04 LTS
Summary

The system could be made to crash under certain conditions.

Software description
  • linux-hwe - Linux hardware enablement (HWE) kernel
Details

USN-3404-1 fixed a vulnerability in the Linux kernel for Ubuntu 17.04.
This update provides the corresponding updates for the Linux Hardware
Enablement (HWE) kernel from Ubuntu 17.04 for Ubuntu 16.04 LTS.

A reference count bug was discovered in the Linux kernel ipx protocol
stack. A local attacker could exploit this flaw to cause a denial of
service or possibly other unspecified problems.

Update instructions

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

Ubuntu 16.04 LTS:
linux-image-4.10.0-33-generic 4.10.0-33.37~16.04.1
linux-image-4.10.0-33-lowlatency 4.10.0-33.37~16.04.1
linux-image-generic-hwe-16.04 4.10.0.33.35
linux-image-lowlatency-hwe-16.04 4.10.0.33.35
linux-image-4.10.0-33-generic-lpae 4.10.0-33.37~16.04.1
linux-image-generic-lpae-hwe-16.04 4.10.0.33.35

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.

linux vulnerabilities

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

  • Ubuntu 14.04 LTS
Summary

Several security issues were fixed in the Linux kernel.

Software description
  • linux - Linux kernel
Details

It was discovered that an out of bounds read vulnerability existed in the
associative array implementation in the Linux kernel. A local attacker
could use this to cause a denial of service (system crash) or expose
sensitive information. (CVE-2016-7914)

It was discovered that a NULL pointer dereference existed in the Direct
Rendering Manager (DRM) driver for VMWare devices in the Linux kernel. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2017-7261)

It was discovered that the USB Cypress HID drivers for the Linux kernel did
not properly validate reported information from the device. An attacker
with physical access could use this to expose sensitive information (kernel
memory). (CVE-2017-7273)

A reference count bug was discovered in the Linux kernel ipx protocol
stack. A local attacker could exploit this flaw to cause a denial of
service or possibly other unspecified problems. (CVE-2017-7487)

Huang Weller discovered that the ext4 filesystem implementation in the
Linux kernel mishandled a needs-flushing-before-commit list. A local
attacker could use this to expose sensitive information. (CVE-2017-7495)

It was discovered that an information leak existed in the set_mempolicy and
mbind compat syscalls in the Linux kernel. A local attacker could use this
to expose sensitive information (kernel memory). (CVE-2017-7616)

Update instructions

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

Ubuntu 14.04 LTS:
linux-image-3.13.0-129-powerpc-e500 3.13.0-129.178
