========================================================================== Ubuntu Security Notice USN-4228-1 January 07, 2020
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)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: linux-image-4.4.0-1064-kvm 4.4.0-1064.71 linux-image-4.4.0-1100-aws 4.4.0-1100.111 linux-image-4.4.0-1127-raspi2 4.4.0-1127.136 linux-image-4.4.0-1131-snapdragon 4.4.0-1131.139 linux-image-4.4.0-171-generic 4.4.0-171.200 linux-image-4.4.0-171-generic-lpae 4.4.0-171.200 linux-image-4.4.0-171-lowlatency 4.4.0-171.200 linux-image-4.4.0-171-powerpc-e500mc 4.4.0-171.200 linux-image-4.4.0-171-powerpc-smp 4.4.0-171.200 linux-image-4.4.0-171-powerpc64-emb 4.4.0-171.200 linux-image-4.4.0-171-powerpc64-smp 4.4.0-171.200 linux-image-aws 4.4.0.1100.104 linux-image-generic 4.4.0.171.179 linux-image-generic-lpae 4.4.0.171.179 linux-image-kvm 4.4.0.1064.64 linux-image-lowlatency 4.4.0.171.179 linux-image-powerpc-e500mc 4.4.0.171.179 linux-image-powerpc-smp 4.4.0.171.179 linux-image-powerpc64-emb 4.4.0.171.179 linux-image-powerpc64-smp 4.4.0.171.179 linux-image-raspi2 4.4.0.1127.127 linux-image-snapdragon 4.4.0.1131.123 linux-image-virtual 4.4.0.171.179
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.
