USN-4114-1: Linux kernel vulnerabilities
2 September 2019
linux, linux-azure, linux-gcp, linux-gke-5.0, linux-hwe, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 19.04
o Ubuntu 18.04 LTS
Summary
Several security issues were fixed in the Linux kernel.
Software Description
o linux - Linux kernel
o linux-azure - Linux kernel for Microsoft Azure Cloud systems
o linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems
o linux-kvm - Linux kernel for cloud environments
o linux-raspi2 - Linux kernel for Raspberry Pi 2
o linux-snapdragon - Linux kernel for Snapdragon processors
o linux-gke-5.0 - Linux kernel for Google Container Engine (GKE) systems
o linux-hwe - Linux hardware enablement (HWE) kernel
Details
Amit Klein and Benny Pinkas discovered that the Linux kernel did not
sufficiently randomize IP ID values generated for connectionless networking
protocols. A remote attacker could use this to track particular Linux devices.
(CVE-2019-10638)
Praveen Pandey discovered that the Linux kernel did not properly validate sent
signals in some situations on PowerPC systems with transactional memory
disabled. A local attacker could use this to cause a denial of service.
(CVE-2019-13648)
It was discovered that the floppy driver in the Linux kernel did not properly
validate meta data, leading to a buffer overread. A local attacker could use
this to cause a denial of service (system crash). (CVE-2019-14283)
It was discovered that the floppy driver in the Linux kernel did not properly
validate ioctl() calls, leading to a division-by-zero. A local attacker could
use this to cause a denial of service (system crash). (CVE-2019-14284)
Jason Wang discovered that an infinite loop vulnerability existed in the virtio
net driver in the Linux kernel. A local attacker in a guest VM could possibly
use this to cause a denial of service in the host system. (CVE-2019-3900)

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.

Summary
USN 4115-1 introduced a regression in the Linux kernel.
Software Description
o linux - Linux kernel
o linux-aws - Linux kernel for Amazon Web Services (AWS) systems
o linux-gke-4.15 - Linux kernel for Google Container Engine (GKE) systems
o linux-kvm - Linux kernel for cloud environments

in the Linux kernel. A physically proximate attacker could use this to cause a
denial of service (system crash). (CVE-2019-15216)

kernel made improper assumptions about the device characteristics. A physically
proximate attacker could use this cause a denial of service (system crash).
(CVE-2019-15218)

not properly validate data size information from the device. A physically
proximate attacker could use this to cause a denial of service (system crash).
(CVE-2019-15221)
Muyu Yu discovered that the CAN implementation in the Linux kernel in some
situations did not properly restrict the field size when processing outgoing
frames. A local attacker with CAP_NET_ADMIN privileges could use this to
execute arbitrary code. (CVE-2019-3701)
Vladis Dronov discovered that the debug interface for the Linux kernel's HID
subsystem did not properly validate passed parameters in some situations. A
local privileged attacker could use this to cause a denial of service (infinite
loop). (CVE-2019-3819)

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.
