CVE-2018-12207

TITLE

Red Hat Security Advisory 2020-0204-01

DESCRIPTION

Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access. Both Microsoft Windows and Microsoft Windows Server are products of Microsoft Corporation. Microsoft Windows is an operating system for personal devices. Microsoft Windows Server is a server operating system. A denial of service vulnerability exists in Microsoft Windows and Windows Server due to the program's improper handling of objects in memory. An attacker could exploit this vulnerability by logging on to an affected system and running a specially crafted application to cause the targeted system to become unresponsive. The following products and versions are affected: Microsoft Windows 10, Windows 10 Version 1607, Windows 10 Version 1709, Windows 10 Version 1803, Windows 10 Version 1809, Windows 10 Version 1903, Windows 7 SP1, Windows 8.1, Windows RT 8.1, Windows Server 2008 R2 SP1, Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019, Windows Server version 1803, Windows Server version 1903. 8.0) - aarch64, noarch, ppc64le, s390x, x86_64 3. Bug Fix(es): * Backport TCP follow-up for small buffers (BZ#1739184) * TCP performance regression after CVE-2019-11478 bug fix (BZ#1743170) * RHEL8.0 - bnx2x link down, caused by transmit timeouts during load test (Marvell/Cavium/QLogic) (L3:) (BZ#1743548) * block: blk-mq improvement (BZ#1780567) * RHEL8.0 - Regression to RHEL7.6 by changing force_latency found during RHEL8.0 validation for SAP HANA on POWER (BZ#1781111) * blk-mq: overwirte performance drops on real MQ device (BZ#1782183) * RHEL8: creating vport takes lot of memory i.e 2GB per vport which leads to drain out system memory quickly. (BZ#1782705) 4.

Software Description: - linux: Linux kernel - linux-hwe: Linux hardware enablement (HWE) kernel - linux-oem-osp1: Linux kernel for OEM processors Details: USN-4184-1 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. Also, the update introduced a regression that broke KVM guests where extended page tables (EPT) are disabled or not supported. This update addresses both issues. We apologize for the inconvenience. Original advisory details: Stephan van Schaik, Alyssa Milburn, Sebastian \xd6sterlund, Pietro Frigo, Kaveh Razavi, Herbert Bos, Cristiano Giuffrida, Giorgi Maisuradze, Moritz Lipp, Michael Schwarz, Daniel Gruss, and Jo Van Bulck discovered that Intel processors using Transactional Synchronization Extensions (TSX) could expose memory contents previously stored in microarchitectural buffers to a malicious process that is executing on the same CPU core. A local attacker could use this to expose sensitive information. (CVE-2019-11135) It was discovered that the Intel i915 graphics chipsets allowed userspace to modify page table entries via writes to MMIO from the Blitter Command Streamer and expose kernel memory information. A local attacker could use this to expose sensitive information or possibly elevate privileges. A local attacker in a guest VM could use this to cause a denial of service (host system crash). (CVE-2018-12207) It was discovered that the Intel i915 graphics chipsets could cause a system hang when userspace performed a read from GT memory mapped input output (MMIO) when the product is in certain low power states. A local attacker could use this to cause a denial of service. (CVE-2019-0154) Hui Peng discovered that the Atheros AR6004 USB Wi-Fi device driver for the Linux kernel did not properly validate endpoint descriptors returned by the device. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15098) Jann Horn discovered a reference count underflow in the shiftfs implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-15791) Jann Horn discovered a type confusion vulnerability in the shiftfs implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-15792) Jann Horn discovered that the shiftfs implementation in the Linux kernel did not use the correct file system uid/gid when the user namespace of a lower file system is not in the init user namespace. A local attacker could use this to possibly bypass DAC permissions or have some other unspecified impact. (CVE-2019-15793) Ori Nimron discovered that the AX25 network protocol implementation in the Linux kernel did not properly perform permissions checks. A local attacker could use this to create a raw socket. (CVE-2019-17052) Ori Nimron discovered that the IEEE 802.15.4 Low-Rate Wireless network protocol implementation in the Linux kernel did not properly perform permissions checks. A local attacker could use this to create a raw socket. (CVE-2019-17053) Ori Nimron discovered that the Appletalk network protocol implementation in the Linux kernel did not properly perform permissions checks. A local attacker could use this to create a raw socket. (CVE-2019-17054) Ori Nimron discovered that the modular ISDN network protocol implementation in the Linux kernel did not properly perform permissions checks. A local attacker could use this to create a raw socket. (CVE-2019-17055) Ori Nimron discovered that the Near field Communication (NFC) network protocol implementation in the Linux kernel did not properly perform permissions checks. A local attacker could use this to create a raw socket. (CVE-2019-17056) Nico Waisman discovered that a buffer overflow existed in the Realtek Wi-Fi driver for the Linux kernel when handling Notice of Absence frames. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-17666) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 19.04: linux-image-5.0.0-36-generic 5.0.0-36.39 linux-image-5.0.0-36-generic-lpae 5.0.0-36.39 linux-image-5.0.0-36-lowlatency 5.0.0-36.39 linux-image-generic 5.0.0.36.38 linux-image-generic-lpae 5.0.0.36.38 linux-image-lowlatency 5.0.0.36.38 linux-image-virtual 5.0.0.36.38 Ubuntu 18.04 LTS: linux-image-5.0.0-1028-oem-osp1 5.0.0-1028.32 linux-image-5.0.0-36-generic 5.0.0-36.39~18.04.1 linux-image-5.0.0-36-generic-lpae 5.0.0-36.39~18.04.1 linux-image-5.0.0-36-lowlatency 5.0.0-36.39~18.04.1 linux-image-generic-hwe-18.04 5.0.0.36.94 linux-image-generic-lpae-hwe-18.04 5.0.0.36.94 linux-image-lowlatency-hwe-18.04 5.0.0.36.94 linux-image-oem-osp1 5.0.0.1028.32 linux-image-virtual-hwe-18.04 5.0.0.36.94 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.

In addition this update provides mitigations for the "TSX Asynchronous Abort" speculative side channel attack. For additional information please refer to https://xenbits.xen.org/xsa/advisory-305.html For the oldstable distribution (stretch), these problems have been fixed in version 4.8.5.final+shim4.10.4-1+deb9u12. Note that this will be the last security update for Xen in the oldstable distribution; upstream support for the 4.8.x branch ended by the end of December 2019. If you rely on security support for your Xen installation an update to the stable distribution (buster) is recommended. For the stable distribution (buster), these problems have been fixed in version 4.11.3+24-g14b62ab3e5-1~deb10u1. We recommend that you upgrade your xen packages.
