Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 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-kvm: Linux kernel for cloud environments - linux-raspi2: Linux kernel for Raspberry Pi 2 - linux-snapdragon: Linux kernel for Snapdragon processors Details: It was discovered that a race condition existed in the GFS2 file system in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2016-10905) It was discovered that the IPv6 implementation in the Linux kernel did not properly validate socket options in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-18509) It was discovered that the USB gadget Midi driver in the Linux kernel contained a double-free vulnerability when handling certain error conditions. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-20961) It was discovered that the XFS file system in the Linux kernel did not properly handle mount failures in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2018-20976) 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 an integer overflow existed in the Linux kernel when reference counting pages, leading to potential use-after-free issues. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-11487) 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 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 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 the Atheros mobile chipset driver in the Linux kernel did not properly validate data in some situations. An attacker could use this to cause a denial of service (system crash). (CVE-2019-15926) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: 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.
