==========================================================================
Ubuntu Security Notice USN-4115-2
September 11, 2019

linux, linux-aws, linux-aws-hwe, linux-azure, linux-gcp, linux-gke-4.15,
linux-hwe, linux-kvm, linux-oracle, linux-raspi2 regression
==========================================================================

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

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

USN 4115-1 introduced a regression 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-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi2: Linux kernel for Raspberry Pi 2
- linux-aws-hwe: Linux kernel for Amazon Web Services (AWS-HWE) systems
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe: Linux hardware enablement (HWE) kernel

Details:

USN 4115-1 fixed vulnerabilities in the Linux 4.15 kernel for Ubuntu
18.04 LTS and Ubuntu 16.04 LTS. Unfortunately, as part of the update,
a regression was introduced that caused a kernel crash when handling
fragmented packets in some situations. This update addresses the issue.

We apologize for the inconvenience.

Original advisory details:

 not properly bounds check the initial HID report sent by the device. A
 physically proximate attacker could use this to cause a denial of service
 (system crash) or possibly execute arbitrary code. (CVE-2019-13631)

 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)

 Tuba Yavuz discovered that a race condition existed in the DesignWare USB3
 DRD Controller device driver in the Linux kernel. A physically proximate
 attacker could use this to cause a denial of service. (CVE-2019-14763)

 It was discovered that an out-of-bounds read existed in the QLogic QEDI
 iSCSI Initiator Driver in the Linux kernel. A local attacker could possibly
 use this to expose sensitive information (kernel memory). (CVE-2019-15090)

 It was discovered that the Raremono AM/FM/SW radio device driver in the
 Linux kernel did not properly allocate memory, leading to a use-after-free.
 A physically proximate attacker could use this to cause a denial of service
 or possibly execute arbitrary code. (CVE-2019-15211)

 It was discovered at a double-free error existed in the USB Rio 500 device
 driver for the Linux kernel. A physically proximate attacker could use this
 to cause a denial of service. (CVE-2019-15212)

 It was discovered that a race condition existed in the Advanced Linux Sound
 Architecture (ALSA) subsystem of the Linux kernel, leading to a potential
 use-after-free. A physically proximate attacker could use this to cause a
 denial of service (system crash) or possibly execute arbitrary code.
 (CVE-2019-15214)

 It was discovered that a race condition existed in the CPiA2 video4linux
 device driver for the Linux kernel, leading to a use-after-free. A
 physically proximate attacker could use this to cause a denial of service
 (system crash) or possibly execute arbitrary code. (CVE-2019-15215)

 It was discovered that a race condition existed in the Softmac USB Prism54
 device driver in the Linux kernel. A physically proximate attacker could
 use this to cause a denial of service (system crash). (CVE-2019-15220)

 It was discovered that a use-after-free vulnerability existed in the
 AppleTalk implementation in the Linux kernel if an error occurs during
 initialization. A local attacker could use this to cause a denial of
 service (system crash). (CVE-2019-15292)

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.
