USN-4228-1: Linux kernel vulnerabilities
更新详情
linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities
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 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)
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 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 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 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)

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
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.
