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:

Eli Biham and Lior Neumann discovered that the Bluetooth implementation in the Linux kernel did not properly validate elliptic curve parameters during Diffie-Hellman key exchange in some situations. An attacker could use this to expose sensitive information. (CVE-2018-5383)

It was discovered that a heap buffer overflow existed in the Marvell Wireless LAN device driver for the Linux kernel. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-10126)

Andrei Vlad Lutas and Dan Lutas discovered that some x86 processors incorrectly handle SWAPGS instructions during speculative execution. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2019-1125)

Jann Horn discovered that a race condition existed in the Linux kernel when performing core dumps. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2019-11599)

It was discovered that the PowerPC dlpar implementation in the Linux kernel did not properly check for allocation errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-12614)

Jann Horn discovered that the ptrace implementation in the Linux kernel did not properly record credentials in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2019-13272)

It was discovered that the Marvell Wireless LAN device driver in the Linux kernel did not properly validate the BSS descriptor. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-3846)

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.
