Ubuntu Security Notice USN-4208-1
December 02, 2019

linux, linux-aws, linux-gcp, linux-gcp-5.3, linux-kvm, linux-oracle
vulnerabilities
==========================================================================

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

- Ubuntu 19.10
- 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-gcp-5.3: Linux kernel for Google Cloud Platform (GCP) 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)

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 ARM Komeda display 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-2019-18810)

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 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, CVE-2019-19061)

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 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
not properly deallocate memory in certain error conditions. A local
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2019-19069)

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)

It was discovered that the AMD Display Engine Driver in the Linux kernel
did not properly deallocate memory in certain error conditions. A local
attack could use this to cause a denial of service (memory exhaustion).
(CVE-2019-19083)

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)

Update instructions:

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

Ubuntu 19.10:
linux-image-5.3.0-1007-oracle 5.3.0-1007.8
linux-image-5.3.0-1008-aws 5.3.0-1008.9
linux-image-5.3.0-1008-kvm 5.3.0-1008.9
linux-image-5.3.0-1009-gcp 5.3.0-1009.10
linux-image-5.3.0-24-generic 5.3.0-24.26
linux-image-5.3.0-24-generic-lpae 5.3.0-24.26
linux-image-5.3.0-24-lowlatency 5.3.0-24.26
linux-image-5.3.0-24-snapdragon 5.3.0-24.26
linux-image-aws 5.3.0.1008.10
linux-image-gcp 5.3.0.1009.10
linux-image-generic 5.3.0.24.28
linux-image-generic-lpae 5.3.0.24.28
linux-image-gke 5.3.0.1009.10
linux-image-kvm 5.3.0.1008.10
linux-image-lowlatency 5.3.0.24.28
linux-image-oracle 5.3.0.1007.8
linux-image-snapdragon 5.3.0.24.28
linux-image-virtual 5.3.0.24.28

Ubuntu 18.04 LTS:
linux-image-5.3.0-1009-gcp 5.3.0-1009.10~18.04.1
linux-image-gcp-edge 5.3.0.1009.9

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.
