Ubuntu Security Notice USN-4210-1
December 03, 2019

linux, linux-aws, linux-aws-hwe, linux-gcp, linux-gke-4.15, linux-hwe,
linux-kvm, linux-oem, linux-oracle, linux-raspi2, linux-snapdragon
vulnerabilities
==========================================================================

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

– Ubuntu 18.04 LTS
– Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
– linux: Linux kernel
– linux-aws: Linux kernel for Amazon Web Services (AWS) systems
– linux-gke-4.15: Linux kernel for Google Container Engine (GKE) systems
– linux-kvm: Linux kernel for cloud environments
– linux-oem: Linux kernel for OEM processors
– linux-oracle: Linux kernel for Oracle Cloud systems
– linux-raspi2: Linux kernel for Raspberry Pi 2
– linux-snapdragon: Linux kernel for Snapdragon processors
– linux-aws-hwe: Linux kernel for Amazon Web Services (AWS-HWE) systems
– linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
– linux-hwe: Linux hardware enablement (HWE) kernel

Details:

It was discovered that a buffer overflow existed in the 802.11 Wi-Fi
configuration interface for the Linux kernel when handling beacon settings.
A local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2019-16746)

Nicolas Waisman discovered that the WiFi driver stack in the Linux kernel
did not properly validate SSID lengths. A physically proximate attacker
could use this to cause a denial of service (system crash).
(CVE-2019-17133)

It was discovered that the ADIS16400 IIO IMU Driver for the Linux kernel
did not properly deallocate memory in certain error conditions. A local
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2019-19060)

It was discovered that the Intel OPA Gen1 Infiniband Driver for the Linux
kernel did not properly deallocate memory in certain error conditions. A
local attacker could use this to cause a denial of service (memory
exhaustion). (CVE-2019-19065)

It was discovered that the Cascoda CA8210 SPI 802.15.4 wireless controller
driver for the Linux kernel did not properly deallocate memory in certain
error conditions. A local attacker could use this to cause a denial of
service (memory exhaustion). (CVE-2019-19075)

Nicolas Waisman discovered that the Chelsio T4/T5 RDMA Driver for the Linux
kernel performed DMA from a kernel stack. A local attacker could use this
to cause a denial of service (system crash). (CVE-2019-17075)

linux-image-virtual-hwe-16.04 4.15.0.72.92

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-4209-1
December 02, 2019

linux, linux-aws, linux-aws-5.0, linux-gcp, linux-gke-5.0, linux-hwe,
linux-kvm, linux-oem-osp1, linux-oracle, linux-oracle-5.0, linux-raspi2
vulnerabilities
==========================================================================

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

– Ubuntu 19.04
– Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
– linux: Linux kernel
– linux-aws: Linux kernel for Amazon Web Services (AWS) systems
– linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
– linux-kvm: Linux kernel for cloud environments
– linux-oracle: Linux kernel for Oracle Cloud systems
– linux-raspi2: Linux kernel for Raspberry Pi 2
– linux-aws-5.0: Linux kernel for Amazon Web Services (AWS) systems
– linux-gke-5.0: Linux kernel for Google Container Engine (GKE) systems
– linux-hwe: Linux hardware enablement (HWE) kernel
– linux-oem-osp1: Linux kernel for OEM processors
– linux-oracle-5.0: Linux kernel for Oracle Cloud systems

Details:

Jann Horn discovered that the OverlayFS and ShiftFS Drivers in the Linux
kernel did not properly handle reference counting during memory mapping
operations when used in conjunction with AUFS. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2019-15794)

It was discovered that there was a memory leak in the Advanced Buffer
Management functionality of the Netronome NFP4000/NFP6000 NIC Driver in the
Linux kernel during certain error scenarios. A local attacker could use
this to cause a denial of service (memory exhaustion). (CVE-2019-19076)

package versions:

attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2019-18810)

It was discovered that the VirtualBox guest driver implementation in the
Linux kernel did not properly deallocate memory in certain error
conditions. A local attacker could use this to cause a denial of service
(memory exhaustion). (CVE-2019-19048)

It was discovered that the AMD Audio CoProcessor Driver for the Linux
kernel did not properly deallocate memory in certain error conditions. A
local attacker with the ability to load modules could use this to cause a
denial of service (memory exhaustion). (CVE-2019-19067)

It was discovered in the Qualcomm FastRPC Driver for the Linux kernel did
