Ubuntu Security Notice USN-3798-2
October 23, 2018

linux-lts-trusty vulnerabilities
==========================================================================

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

- Ubuntu 12.04 ESM

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-lts-trusty: Linux hardware enablement kernel from Trusty for Precise
ESM

Details:

USN-3798-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu
12.04 LTS.

Dmitry Vyukov discovered that the key management subsystem in the Linux
kernel did not properly restrict adding a key that already exists but is
negatively instantiated. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2015-8539)

It was discovered that a use-after-free vulnerability existed in the device
driver for XCeive xc2028/xc3028 tuners in the Linux kernel. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2016-7913)

Pengfei Ding (䞁鹏飞), Chenfu Bao (包沉浮), and Lenx Wei (韊韬)
discovered a race condition in the generic SCSI driver (sg) of the Linux
kernel. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2017-0794)

Eric Biggers discovered that the key management subsystem in the Linux
kernel did not properly restrict adding a key that already exists but is
uninstantiated. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2017-15299)

It was discovered that a NULL pointer dereference could be triggered in the
OCFS2 file system implementation in the Linux kernel. A local attacker
could use this to cause a denial of service (system crash).
(CVE-2017-18216)

Luo Quan and Wei Yang discovered that a race condition existed in the
Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel when
handling ioctl()s. A local attacker could use this to cause a denial of
service (system deadlock). (CVE-2018-1000004)

范韙飞 discovered that a race condition existed in the Advanced Linux
Sound Architecture (ALSA) subsystem of the Linux kernel that could lead to
a use- after-free or an out-of-bounds buffer access. A local attacker with
access to /dev/snd/seq could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2018-7566)

It was discovered that a buffer overflow existed in the NFC Logical Link
Control Protocol (llcp) implementation in the Linux kernel. An attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2018-9518)

Update instructions:

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

Ubuntu 12.04 ESM:
linux-image-3.13.0-161-generic 3.13.0-161.211~precise1
linux-image-3.13.0-161-generic-lpae 3.13.0-161.211~precise1
linux-image-generic-lpae-lts-trusty 3.13.0.161.151
linux-image-generic-lts-trusty 3.13.0.161.151

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.
