Ubuntu Security Notice USN-3342-1
June 29, 2017

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

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

- - Ubuntu 16.10

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- - linux: Linux kernel
- - linux-raspi2: Linux kernel for Raspberry Pi 2

Details:

USN 3326-1 fixed a vulnerability in the Linux kernel. However, that
fix introduced regressions for some Java applications. This update
addresses the issue. We apologize for the inconvenience.

It was discovered that a use-after-free flaw existed in the filesystem
encryption subsystem in the Linux kernel. A local attacker could use this
to cause a denial of service (system crash). (CVE-2017-7374)

Roee Hay discovered that the parallel port printer driver in the Linux
kernel did not properly bounds check passed arguments. A local attacker
with write access to the kernel command line arguments could use this to
execute arbitrary code. (CVE-2017-1000363)

Ingo Molnar discovered that the VideoCore DRM driver in the Linux kernel
did not return an error after detecting certain overflows. A local attacker
could exploit this issue to cause a denial of service (OOPS).
(CVE-2017-5577)

Li Qiang discovered that an integer overflow vulnerability 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) or possibly execute arbitrary code. (CVE-2017-7294)

It was discovered that a double-free vulnerability existed in the IPv4
stack of the Linux kernel. An attacker could use this to cause a denial of
service (system crash). (CVE-2017-8890)

Andrey Konovalov discovered an IPv6 out-of-bounds read error in the Linux
kernel's IPv6 stack. A local attacker could cause a denial of service or
potentially other unspecified problems. (CVE-2017-9074)

Andrey Konovalov discovered a flaw in the handling of inheritance in the
Linux kernel's IPv6 stack. A local user could exploit this issue to cause a
denial of service or possibly other unspecified problems. (CVE-2017-9075)

It was discovered that dccp v6 in the Linux kernel mishandled inheritance.
A local attacker could exploit this issue to cause a denial of service or
potentially other unspecified problems. (CVE-2017-9076)

It was discovered that the transmission control protocol (tcp) v6 in the
Linux kernel mishandled inheritance. A local attacker could exploit this
issue to cause a denial of service or potentially other unspecified
problems. (CVE-2017-9077)

It was discovered that the IPv6 stack in the Linux kernel was performing
its over write consistency check after the data was actually overwritten. A
local attacker could exploit this flaw to cause a denial of service (system
crash). (CVE-2017-9242)

Update instructions:

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

Ubuntu 16.10:
  linux-image-4.8.0-1042-raspi2   4.8.0-1042.46
  linux-image-4.8.0-58-generic    4.8.0-58.63
  linux-image-4.8.0-58-generic-lpae  4.8.0-58.63
  linux-image-4.8.0-58-lowlatency  4.8.0-58.63
  linux-image-4.8.0-58-powerpc-e500mc  4.8.0-58.63
  linux-image-4.8.0-58-powerpc-smp  4.8.0-58.63
  linux-image-4.8.0-58-powerpc64-emb  4.8.0-58.63
  linux-image-generic             4.8.0.58.71
  linux-image-generic-lpae        4.8.0.58.71
  linux-image-lowlatency          4.8.0.58.71
  linux-image-powerpc-e500mc      4.8.0.58.71
  linux-image-powerpc-smp         4.8.0.58.71
  linux-image-powerpc64-emb       4.8.0.58.71
  linux-image-powerpc64-smp       4.8.0.58.71
  linux-image-raspi2              4.8.0.1042.46
  linux-image-virtual             4.8.0.58.71

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.

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.

Ubuntu Security Notice USN-3344-2
June 29, 2017

linux-lts-xenial 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-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty

Details:

USN-3344-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu
14.04 LTS.

USN 3334-1 fixed a vulnerability in the Linux kernel. However, that
fix introduced regressions for some Java applications. This update
addresses the issue. We apologize for the inconvenience.

Roee Hay discovered that the parallel port printer driver in the Linux
kernel did not properly bounds check passed arguments. A local attacker
with write access to the kernel command line arguments could use this to
execute arbitrary code. (CVE-2017-1000363)

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)

It was discovered that a double-free vulnerability existed in the IPv4
stack of the Linux kernel. An attacker could use this to cause a denial of
service (system crash). (CVE-2017-8890)

Andrey Konovalov discovered an IPv6 out-of-bounds read error in the Linux
kernel's IPv6 stack. A local attacker could cause a denial of service or
potentially other unspecified problems. (CVE-2017-9074)

Andrey Konovalov discovered a flaw in the handling of inheritance in the
Linux kernel's IPv6 stack. A local user could exploit this issue to cause a
denial of service or possibly other unspecified problems. (CVE-2017-9075)

It was discovered that dccp v6 in the Linux kernel mishandled inheritance.
A local attacker could exploit this issue to cause a denial of service or
potentially other unspecified problems. (CVE-2017-9076)

It was discovered that the transmission control protocol (tcp) v6 in the
Linux kernel mishandled inheritance. A local attacker could exploit this
issue to cause a denial of service or potentially other unspecified
problems. (CVE-2017-9077)

It was discovered that the IPv6 stack in the Linux kernel was performing
its over write consistency check after the data was actually overwritten. A
local attacker could exploit this flaw to cause a denial of service (system
crash). (CVE-2017-9242)

Update instructions:

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

Ubuntu 14.04 LTS:
  linux-image-4.4.0-83-generic    4.4.0-83.106~14.04.1
  linux-image-4.4.0-83-generic-lpae  4.4.0-83.106~14.04.1

  linux-image-4.4.0-83-powerpc-smp  4.4.0-83.106~14.04.1
  linux-image-4.4.0-83-powerpc64-emb  4.4.0-83.106~14.04.1
  linux-image-4.4.0-83-powerpc64-smp  4.4.0-83.106~14.04.1
  linux-image-generic-lpae-lts-xenial  4.4.0.83.68
  linux-image-generic-lts-xenial  4.4.0.83.68
  linux-image-lowlatency-lts-xenial  4.4.0.83.68
  linux-image-powerpc-e500mc-lts-xenial  4.4.0.83.68
  linux-image-powerpc-smp-lts-xenial  4.4.0.83.68
  linux-image-powerpc64-emb-lts-xenial  4.4.0.83.68
  linux-image-powerpc64-smp-lts-xenial  4.4.0.83.68
