Ubuntu Security Notice USN-3798-1

Ubuntu Security Notice USN-3798-1
Posted Oct 23, 2018
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3798-1 - 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 or possibly execute arbitrary code. 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 or possibly execute arbitrary code. Various other issues were also addressed.

==========================================================================

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:

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 (a,e1ePS), Chenfu Bao (aae2aeu(r)), and Lenx Wei (e|e!)
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)

ee3/4ePS 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 14.04 LTS:
linux-image-3.13.0-161-generic 3.13.0-161.211
linux-image-3.13.0-161-generic-lpae 3.13.0-161.211
linux-image-3.13.0-161-lowlatency 3.13.0-161.211
linux-image-3.13.0-161-powerpc-e500 3.13.0-161.211
linux-image-3.13.0-161-powerpc-e500mc 3.13.0-161.211
linux-image-3.13.0-161-powerpc-smp 3.13.0-161.211
linux-image-3.13.0-161-powerpc64-emb 3.13.0-161.211
linux-image-3.13.0-161-powerpc64-smp 3.13.0-161.211
linux-image-generic 3.13.0.161.171
linux-image-generic-lpae 3.13.0.161.171
linux-image-highbank 3.13.0.161.171
linux-image-lowlatency 3.13.0.161.171
linux-image-powerpc-e500 3.13.0.161.171
linux-image-powerpc-e500mc 3.13.0.161.171
linux-image-powerpc-smp 3.13.0.161.171
linux-image-powerpc64-emb 3.13.0.161.171
linux-image-powerpc64-smp 3.13.0.161.171

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.
