security advisorydenial of serviceUbuntuUbuntu 19.04 and 18.04 LTS: USN-4147-1 Critical: Kernel Crash Threats
Several security issues were fixed in the Linux kernel.. =========================================================================Ubuntu Security Notice USN-4147-1 October 04, 2019 linux, linux-aws, 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-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-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: It was discovered that the Intel Wi-Fi device driver in the Linux kernel did not properly validate certain Tunneled Direct Link Setup (TDLS). A physically proximate attacker could use this to cause a denial of service (Wi-Fi disconnect). (CVE-2019-0136) It was discovered that the Bluetooth UART implementation in the Linux kernel did not properly check for missing tty operations. A local attacker could use this to cause a denial of service. (CVE-2019-10207) It was discovered that the GTCO tablet input driver in the Linux kernel did 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) 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) Hui Peng and Mathias Payer discovered that the USB audio driver for the Linux kernel did not properly validate device meta data. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15117) Hui Peng and Mathias Payer discovered that the USB audio driver for the Linux kernel improperly performed recursion while handling device meta data. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15118) 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 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) Benjamin Moody discovered that the XFS file system in the Linux kernel did not properly handle an error condition when out of disk quota. A local attacker could possibly use this to cause a denial of service. (CVE-2019-15538) It was discovered that the Hisilicon HNS3 ethernet device driver in the Linux kernel contained an out of bounds access vulnerability. A local attacker could use this to possibly cause a denial of service (system crash). (CVE-2019-15925) It was discovered that the Atheros mobile chipset driver in the Linux kernel did notproperly validate data in some situations. An attacker could use this to cause a denial of service (system crash). (CVE-2019-15926) Daniele Antonioli, Nils Ole Tippenhauer, and Kasper B. Rasmussen discovered that the Bluetooth protocol BR/EDR specification did not properly require sufficiently strong encryption key lengths. A physically proximate attacker could use this to expose sensitive information. (CVE-2019-9506) It was discovered that ZR364XX Camera USB device driver for the Linux kernel did not properly initialize memory. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15217) It was discovered that the Siano USB MDTV receiver device driver in the Linux 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) It was discovered that the Line 6 POD USB device driver in the Linux kernel did 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) It was discovered that the Line 6 USB driver for the Linux kernel contained a race condition when the device was disconnected. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15223) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 19.04: linux-image-5.0.0-1018-aws 5.0.0-1018.20 linux-image-5.0.0-1019-kvm 5.0.0-1019.20 linux-image-5.0.0-1019-raspi2 5.0.0-1019.19 linux-image-5.0.0-1020-gcp 5.0.0-1020.20 linux-image-5.0.0-1022-azure 5.0.0-1022.23 linux-image-5.0.0-1023-snapdragon 5.0.0-1023.24 linux-image-5.0.0-31-generic 5.0.0-31.33 linux-image-5.0.0-31-generic-lpae 5.0.0-31.33 linux-image-5.0.0-31-lowlatency 5.0.0-31.33 linux-image-aws 5.0.0.1018.19 linux-image-azure 5.0.0.1022.21 linux-image-gcp 5.0.0.1020.46 linux-image-generic 5.0.0.31.32 linux-image-generic-lpae 5.0.0.31.32 linux-image-gke 5.0.0.1020.46 linux-image-kvm 5.0.0.1019.19 linux-image-lowlatency 5.0.0.31.32 linux-image-raspi2 5.0.0.1019.16 linux-image-snapdragon 5.0.0.1023.16 linux-image-virtual 5.0.0.31.32 Ubuntu 18.04 LTS: linux-image-5.0.0-1020-gke 5.0.0-1020.20~18.04.1 linux-image-5.0.0-31-generic 5.0.0-31.33~18.04.1 linux-image-5.0.0-31-generic-lpae 5.0.0-31.33~18.04.1 linux-image-5.0.0-31-lowlatency 5.0.0-31.33~18.04.1 linux-image-generic-hwe-18.04 5.0.0.31.88 linux-image-generic-lpae-hwe-18.04 5.0.0.31.88 linux-image-gke-5.0 5.0.0.1020.9 linux-image-lowlatency-hwe-18.04 5.0.0.31.88 linux-image-snapdragon-hwe-18.04 5.0.0.31.88 linux-image-virtual-hwe-18.04 5.0.0.31.88 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.
