Ben Hawkes discovered that the Linux netfilter implementation did not
correctly perform validation when handling IPT_SO_SET_REPLACE events. A
local unprivileged attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code with administrative
privileges. (CVE-2016-3134)

It was discovered that the Linux kernel did not properly enforce rlimits
for file descriptors sent over UNIX domain sockets. A local attacker could
use this to cause a denial of service. (CVE-2013-4312)

It was discovered that a race condition existed when handling heartbeat-
timeout events in the SCTP implementation of the Linux kernel. A remote
attacker could use this to cause a denial of service. (CVE-2015-8767)

Andy Lutomirski discovered a race condition in the Linux kernel’s
translation lookaside buffer (TLB) handling of flush events. A local
attacker could use this to cause a denial of service or possibly leak
sensitive information. (CVE-2016-2069)

Andrey Konovalov discovered that the ALSA USB MIDI driver incorrectly
performed a double-free. A local attacker with physical access could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code with administrative privileges. (CVE-2016-2384)

Dmitry Vyukov discovered that the Advanced Linux Sound Architecture (ALSA)
framework did not verify that a FIFO was attached to a client before
attempting to clear it. A local attacker could use this to cause a denial
of service (system crash). (CVE-2016-2543)

Dmitry Vyukov discovered that a race condition existed in the Advanced
Linux Sound Architecture (ALSA) framework between timer setup and closing
of the client, resulting in a use-after-free. A local attacker could use
this to cause a denial of service. (CVE-2016-2544)

Dmitry Vyukov discovered a race condition in the timer handling
implementation of the Advanced Linux Sound Architecture (ALSA) framework,

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.

exim4 vulnerabilities

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

• Ubuntu 15.10
• Ubuntu 14.04 LTS
• Ubuntu 12.04 LTS

Summary

Several security issues were fixed in Exim.

Software description

• exim4
  – Exim is a mail transport agent

Details

It was discovered that Exim incorrectly filtered environment variables when
used with the perl_startup configuration option. If the perl_startup option
was enabled, a local attacker could use this issue to escalate their
privileges to the root user. This issue has been fixed by having Exim clean
the complete execution environment by default on startup, including any
subprocesses such as transports that call other programs. This change in
behaviour may break existing installations and can be adjusted by using two
new configuration options, keep_environment and add_environment.
(CVE-2016-1531)

Patrick William discovered that Exim incorrectly expanded mathematical
comparisons twice. A local attacker could possibly use this issue to
perform arbitrary file operations as the Exim user. This issue only
affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-2972)

Update instructions

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

Ubuntu 15.10:

exim4-daemon-heavy

4.86-3ubuntu1.1

exim4-daemon-light

4.86-3ubuntu1.1

Ubuntu 14.04 LTS:

exim4-daemon-heavy

4.82-3ubuntu2.1

exim4-daemon-custom

4.82-3ubuntu2.1

exim4-daemon-light

4.82-3ubuntu2.1

Ubuntu 12.04 LTS:

4.76-3ubuntu3.3

exim4-daemon-custom

4.76-3ubuntu3.3

exim4-daemon-light

4.76-3ubuntu3.3

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

This update introduces environment filtering, which may break certain
existing installations. After performing a standard system update, the new
keep_environment and add_environment configurations options can be used
to adjust the new behaviour.
