========================================================================= Ubuntu Security Notice USN-4225-1 January 07, 2020 linux, linux-aws, linux-azure, linux-azure-5.3, linux-gcp, linux-gcp-5.3, linux-kvm, linux-oracle, linux-raspi2 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-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-oracle: Linux kernel for Oracle Cloud systems - linux-raspi2: Linux kernel for Raspberry Pi 2 - linux-azure-5.3: Linux kernel for Microsoft Azure Cloud systems - linux-gcp-5.3: Linux kernel for Google Cloud Platform (GCP) systems Details: It was discovered that a heap-based buffer overflow existed in the Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895, CVE-2019-14901) It was discovered that a heap-based buffer overflow existed in the Marvell Libertas WLAN Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14896, CVE-2019-14897) It was discovered that the Fujitsu ES network device driver for the Linux kernel did not properly check for errors in some situations, leading to a NULL pointer dereference. A local attacker could use this to cause a denial of service. (CVE-2019-16231) Anthony Steinhauser discovered that the Linux kernel did not properly perform Spectre_RSB mitigations to all processors for PowerPC architecture systems in some situations. A local attacker could use this to expose sensitive information. (CVE-2019-18660) It was discovered that the Broadcom V3D DRI driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19044) It was discovered that the Mellanox Technologies Innova driver in the Linux kernel did not properly deallocate memory in certain failure conditions. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19045) It was discovered that the Mellanox Technologies ConnectX driver in the Linux kernel did not properly deallocate memory in certain failure conditions. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19047) It was discovered that the Intel WiMAX 2400 driver in the Linux kernel did not properly deallocate memory in certain situations. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19051) It was discovered that Geschwister Schneider USB CAN interface driver in the Linux kernel did not properly deallocate memory in certain failure conditions. A physically proximate attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19052) It was discovered that the netlink-based 802.11 configuration interface in the Linux kernel did not deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19055) It was discovered that the event tracing subsystem of the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19072) It was discovered that the driver for memoryless force-feedback input devices in the Linux kernel contained a use-after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2019-19524) It was discovered that the Microchip CAN BUS Analyzer driver in the Linux kernel contained a use-after-free vulnerability on device disconnect. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-19529) It was discovered that the PEAK-System Technik USB driver in the Linux kernel did not properly sanitize memory before sending it to the device. A physically proximate attacker could use this to expose sensitive information (kernel memory). (CVE-2019-19534) Tristan Madani discovered that the ALSA timer implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-19807) It was discovered that the DesignWare USB3 controller driver in the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2019-18813) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 19.10: linux-image-5.3.0-1008-oracle 5.3.0-1008.9 linux-image-5.3.0-1009-aws 5.3.0-1009.10 linux-image-5.3.0-1009-azure 5.3.0-1009.10 linux-image-5.3.0-1009-kvm 5.3.0-1009.10 linux-image-5.3.0-1011-gcp 5.3.0-1011.12 linux-image-5.3.0-1015-raspi2 5.3.0-1015.17 linux-image-5.3.0-26-generic 5.3.0-26.28 linux-image-5.3.0-26-generic-lpae 5.3.0-26.28 linux-image-5.3.0-26-lowlatency 5.3.0-26.28 linux-image-5.3.0-26-snapdragon 5.3.0-26.28 linux-image-aws 5.3.0.1009.11 linux-image-azure 5.3.0.1009.27 linux-image-gcp 5.3.0.1011.12 linux-image-generic 5.3.0.26.30 linux-image-generic-lpae 5.3.0.26.30 linux-image-gke 5.3.0.1011.12 linux-image-kvm 5.3.0.1009.11 linux-image-lowlatency 5.3.0.26.30 linux-image-oracle 5.3.0.1008.9 linux-image-raspi2 5.3.0.1015.12 linux-image-snapdragon 5.3.0.26.30 linux-image-virtual 5.3.0.26.30 Ubuntu 18.04 LTS: linux-image-5.3.0-1009-azure 5.3.0-1009.10~18.04.1 linux-image-5.3.0-1010-gcp 5.3.0-1010.11~18.04.1 linux-image-azure-edge 5.3.0.1009.9 linux-image-gcp-edge 5.3.0.1010.10 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.
