========================================================================== Ubuntu Security Notice USN-4114-1 September 02, 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:
- Ubuntu 19.04 - Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux: Linux kernel - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-kvm: Linux kernel for cloud environments - linux-raspi2: Linux kernel for Raspberry Pi 2 - linux-snapdragon: Linux kernel for Snapdragon processors - linux-gke-5.0: Linux kernel for Google Container Engine (GKE) systems - 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)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 19.04: linux-image-5.0.0-1015-gcp 5.0.0-1015.15 linux-image-5.0.0-1015-kvm 5.0.0-1015.16 linux-image-5.0.0-1015-raspi2 5.0.0-1015.15 linux-image-5.0.0-1018-azure 5.0.0-1018.19 linux-image-5.0.0-1019-snapdragon 5.0.0-1019.20 linux-image-5.0.0-27-generic 5.0.0-27.28 linux-image-5.0.0-27-generic-lpae 5.0.0-27.28 linux-image-5.0.0-27-lowlatency 5.0.0-27.28 linux-image-azure 5.0.0.1018.17 linux-image-gcp 5.0.0.1015.41 linux-image-generic 5.0.0.27.28 linux-image-generic-lpae 5.0.0.27.28 linux-image-gke 5.0.0.1015.41 linux-image-kvm 5.0.0.1015.15 linux-image-lowlatency 5.0.0.27.28 linux-image-raspi2 5.0.0.1015.12 linux-image-snapdragon 5.0.0.1019.12 linux-image-virtual 5.0.0.27.28
Ubuntu 18.04 LTS: linux-image-5.0.0-1015-gke 5.0.0-1015.15~18.04.1 linux-image-5.0.0-1018-azure 5.0.0-1018.19~18.04.1 linux-image-5.0.0-27-generic 5.0.0-27.28~18.04.1 linux-image-5.0.0-27-generic-lpae 5.0.0-27.28~18.04.1 linux-image-5.0.0-27-lowlatency 5.0.0-27.28~18.04.1 linux-image-azure 5.0.0.1018.28 linux-image-generic-hwe-18.04 5.0.0.27.84 linux-image-generic-lpae-hwe-18.04 5.0.0.27.84 linux-image-gke-5.0 5.0.0.1015.5 linux-image-lowlatency-hwe-18.04 5.0.0.27.84 linux-image-snapdragon-hwe-18.04 5.0.0.27.84 linux-image-virtual-hwe-18.04 5.0.0.27.84
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.
