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 Details: USN-4186-1 fixed vulnerabilities in the Linux kernel. It was discovered that the kernel fix for CVE-2019-0155 (i915 missing Blitter Command Streamer check) was incomplete on 64-bit Intel x86 systems. This update addresses the issue. We apologize for the inconvenience. Original advisory details: Stephan van Schaik, Alyssa Milburn, Sebastian Österlund, Pietro Frigo, It was discovered that the Intel i915 graphics chipsets allowed userspace Deepak Gupta discovered that on certain Intel processors, the Linux kernel It was discovered that the Intel i915 graphics chipsets could cause a Hui Peng discovered that the Atheros AR6004 USB Wi-Fi device driver for the It was discovered that a buffer overflow existed in the 802.11 Wi-Fi Ori Nimron discovered that the AX25 network protocol implementation in the Ori Nimron discovered that the IEEE 802.15.4 Low-Rate Wireless network Ori Nimron discovered that the Appletalk network protocol implementation in Ori Nimron discovered that the modular ISDN network protocol implementation Ori Nimron discovered that the Near field Communication (NFC) network Nico Waisman discovered that a buffer overflow existed in the Realtek Wi-Fi Maddie Stone discovered that the Binder IPC Driver implementation in the Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: Please note that mitigating the TSX (CVE-2019-11135) and i915 (CVE-2019-0154) issues requires corresponding microcode and graphics firmware updates respectively. 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.
