TITLE

Linux kernel Buffer error vulnerability

DESCRIPTION

There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. 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. 7) - aarch64, noarch, ppc64le 3. Bug Fix(es): * Kernel panic on job cleanup, related to SyS_getdents64 (BZ#1702057) * Kernel modules generated incorrectly when system is localized to non-English language (BZ#1705285) * RHEL-Alt-7.6 - Fixup tlbie vs store ordering issue on POWER9 (BZ#1756270) 4. Bugs fixed (https://bugzilla.redhat.com/): 1581650 - CVE-2018-3693 Kernel: speculative bounds check bypass store 1641878 - CVE-2018-18559 kernel: Use-after-free due to race condition in AF_PACKET implementation 1678685 - CVE-2019-8912 kernel: af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr 1703063 - CVE-2019-11487 kernel: Count overflow in FUSE request leading to use-after-free issues. ========================================================================== Ubuntu Security Notice USN-4157-1 October 17, 2019 linux, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 19.04 Summary: Several security issues were fixed in the Linux kernel. (CVE-2019-14814, CVE-2019-14815, CVE-2019-14816) Matt Delco discovered that the KVM hypervisor implementation in the Linux kernel did not properly perform bounds checking when handling coalesced MMIO write operations. A local attacker with write access to /dev/kvm could use this to cause a denial of service (system crash). (CVE-2019-14821) Hui Peng and Mathias Payer discovered that the 91x Wi-Fi driver in the Linux kernel did not properly handle error conditions on initialization, leading to a double-free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15504) It was discovered that the Technisat DVB-S/S2 USB device driver in the Linux kernel contained a buffer overread. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-15505) Brad Spengler discovered that a Spectre mitigation was improperly implemented in the ptrace susbsystem of the Linux kernel. A local attacker could possibly use this to expose sensitive information. (CVE-2019-15902) It was discovered that the IPv6 RDS implementation in the Linux kernel did not properly initialize fields in a data structure returned to user space. A local attacker could use this to expose sensitive information (kernel memory). Please note that the RDS protocol is blacklisted in Ubuntu by default. A local attacker could use this to escalate privileges. (CVE-2019-2181) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 19.04: linux-image-5.0.0-1019-aws 5.0.0-1019.21 linux-image-5.0.0-1020-kvm 5.0.0-1020.21 linux-image-5.0.0-1020-raspi2 5.0.0-1020.20 linux-image-5.0.0-1021-gcp 5.0.0-1021.21 linux-image-5.0.0-1023-azure 5.0.0-1023.24 linux-image-5.0.0-1024-snapdragon 5.0.0-1024.25 linux-image-5.0.0-32-generic 5.0.0-32.34 linux-image-5.0.0-32-generic-lpae 5.0.0-32.34 linux-image-5.0.0-32-lowlatency 5.0.0-32.34 linux-image-aws 5.0.0.1019.20 linux-image-azure 5.0.0.1023.22 linux-image-gcp 5.0.0.1021.47 linux-image-generic 5.0.0.32.33 linux-image-generic-lpae 5.0.0.32.33 linux-image-gke 5.0.0.1021.47 linux-image-kvm 5.0.0.1020.20 linux-image-lowlatency 5.0.0.32.33 linux-image-raspi2 5.0.0.1020.17 linux-image-snapdragon 5.0.0.1024.17 linux-image-virtual 5.0.0.32.33 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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2020:0653-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2020:0653 Issue date: 2020-03-03 CVE Names: CVE-2019-14816 CVE-2019-14895 CVE-2019-17133 ==================================================================== 1.
