Ubuntu Security Notice 4008-3 - USN-4008-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 ESM. Robert Swiecki discovered that the Linux kernel did not properly apply Address Space Layout Randomization in some situations for setuid elf binaries. A local attacker could use this to improve the chances of exploiting an existing vulnerability in a setuid elf binary. Various other issues were also addressed.

linux-lts-xenial, linux-aws vulnerabilities
==========================================================================

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

- Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty

Details:

USN-4008-1 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 ESM.

Robert Święcki discovered that the Linux kernel did not properly apply
Address Space Layout Randomization (ASLR) in some situations for setuid elf
binaries. A local attacker could use this to improve the chances of
exploiting an existing vulnerability in a setuid elf binary.
(CVE-2019-11190)

It was discovered that a null pointer dereference vulnerability existed in
the LSI Logic MegaRAID driver in the Linux kernel. A local attacker could
use this to cause a denial of service (system crash). (CVE-2019-11810)

It was discovered that a race condition leading to a use-after-free existed
in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux
kernel. The RDS protocol is blacklisted by default in Ubuntu. If enabled, a
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2019-11815)

Federico Manuel Bento discovered that the Linux kernel did not properly
apply Address Space Layout Randomization (ASLR) in some situations for
setuid a.out binaries. A local attacker could use this to improve the
chances of exploiting an existing vulnerability in a setuid a.out binary.
(CVE-2019-11191)

As a hardening measure, this update disables a.out support.

Update instructions:

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

Ubuntu 14.04 ESM:
linux-image-4.4.0-1045-aws 4.4.0-1045.48
linux-image-4.4.0-150-generic 4.4.0-150.176~14.04.1
linux-image-4.4.0-150-generic-lpae 4.4.0-150.176~14.04.1
linux-image-4.4.0-150-lowlatency 4.4.0-150.176~14.04.1
linux-image-aws 4.4.0.1045.46
linux-image-generic-lpae-lts-xenial 4.4.0.150.132
linux-image-generic-lts-xenial 4.4.0.150.132
linux-image-lowlatency-lts-xenial 4.4.0.150.132

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.
