security advisorydenial of serviceubuntuUbuntu 18.04 LTS: USN-4440-1: Critical Kernel Issues Addressed
Several security issues were fixed in the Linux kernel.. =========================================================================Ubuntu Security Notice USN-4440-1 July 27, 2020 linux-hwe, linux-azure-5.3, linux-gcp-5.3, linux-gke-5.3, linux-hwe, linux-oracle-5.3 vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 18.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-azure-5.3: linux kernel for microsoft azure cloud systems - linux-gcp-5.3: Linux kernel for Google Cloud Platform (GCP) systems - linux-gke-5.3: Linux kernel for Google Container Engine (GKE) systems - linux-hwe: Linux hardware enablement (HWE) kernel - linux-oracle-5.3: Linux kernel for Oracle Cloud systems Details: It was discovered that the network block device (nbd) implementation in the Linux kernel did not properly check for error conditions in some situations. An attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-16089) It was discovered that the kernel-> user space relay implementation in the Linux kernel did not properly check return values in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-19462) Chuhong Yuan discovered that go7007 USB audio device driver in the Linux kernel did not properly deallocate memory in some failure conditions. A physically proximate attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-20810) Jason A. Donenfeld discovered that the ACPI implementation in the Linux kernel did not properly restrict loading SSDT code from an EFI variable. A privileged attacker could use this to bypass Secure Boot lockdown restrictions and execute arbitrary code in the kernel. (CVE-2019-20908) It was discovered that the elf handling code in the Linux kernel did not initialize memory before using it in certain situations. Alocal attacker could use this to possibly expose sensitive information (kernel memory). (CVE-2020-10732) Fan Yang discovered that the mremap implementation in the Linux kernel did not properly handle DAX Huge Pages. A local attacker with access to DAX storage could use this to gain administrative privileges. (CVE-2020-10757) It was discovered that the Linux kernel did not correctly apply Speculative Store Bypass Disable (SSBD) mitigations in certain situations. A local attacker could possibly use this to expose sensitive information. (CVE-2020-10766) It was discovered that the Linux kernel did not correctly apply Indirect Branch Predictor Barrier (IBPB) mitigations in certain situations. A local attacker could possibly use this to expose sensitive information. (CVE-2020-10767) It was discovered that the Linux kernel could incorrectly enable indirect branch speculation after it has been disabled for a process via a prctl() call. A local attacker could possibly use this to expose sensitive information. (CVE-2020-10768) Mauricio Faria de Oliveira discovered that the aufs implementation in the Linux kernel improperly managed inode reference counts in the vfsub_dentry_open() method. A local attacker could use this vulnerability to cause a denial of service. (CVE-2020-11935) It was discovered that the Virtual Terminal keyboard driver in the Linux kernel contained an integer overflow. A local attacker could possibly use this to have an unspecified impact. (CVE-2020-13974) Jason A. Donenfeld discovered that the ACPI implementation in the Linux kernel did not properly restrict loading ACPI tables via configfs. A privileged attacker could use this to bypass Secure Boot lockdown restrictions and execute arbitrary code in the kernel. (CVE-2020-15780) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-5.3.0-1030-oracle 5.3.0-1030.32~18.04.1 linux-image-5.3.0-1032-gcp 5.3.0-1032.34~18.04.1 linux-image-5.3.0-1032-gke 5.3.0-1032.34~18.04.1 linux-image-5.3.0-1034-azure 5.3.0-1034.35~18.04.1 linux-image-5.3.0-64-generic 5.3.0-64.58~18.04.1 linux-image-5.3.0-64-generic-lpae 5.3.0-64.58~18.04.1 linux-image-5.3.0-64-lowlatency 5.3.0-64.58~18.04.1 linux-image-azure 5.3.0.1034.30 linux-image-gcp 5.3.0.1032.26 linux-image-gke-5.3 5.3.0.1032.17 linux-image-gkeop-5.3 5.3.0.64.120 linux-image-oracle 5.3.0.1030.27 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.

security advisorybug fixmemory corruptionScientific Linux: SLSA-2017:0892-1 Important: Kernel Memory Corruption Risk
Important: kernel security and bug fix update. Date: Tue, 11 Apr 2017 18:47:10 -0000 Reply-To: scientific-linux-users@ Sender: Security Errata for Scientific Linux From: Pat Riehecky Subject: Security ERRATA Important: kernel on SL6.x i386/x86_64 MIME-Version: 1.0 Message-ID: Synopsis: Important: kernel security and bug fix update Advisory ID: SLSA-2017:0892-1 Issue Date: 2017-04-11 CVE Numbers: CVE-2016-7910 CVE-2017-2636 -- Security Fix(es): * A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that can lead to double free. A local, unprivileged user able to set the HDLC line discipline on the tty device could use this flaw to increase their privileges on the system. (CVE-2017-2636, Important) * A flaw was found in the Linux kernel's implementation of seq_file where a local attacker could manipulate memory in the put() function pointer. This could lead to memory corruption and possible privileged escalation. (CVE-2016-7910, Moderate) Bug Fix(es): * Previously, Chelsio firmware included an incorrectly-formatted firmware bin file. As a consequence, the firmware could not be flashed. This update provides a firmware bin file that is formatted correctly. As a result, Chelsio firmware can now be flashed successfully. * When multiple simultaneous processes attempted to read from the /proc/stat file, spinlock overhead was generated on Non-Uniform Memory Access (NUMA) systems. Consequently, a large amount of CPU was consumed. With this update, the underlying source code has been fixed to avoid taking spinlock when the interrupt line does not exist. As a result, the spinlock overhead is now generated less often, and multiple simultaneous processes can now read /proc/stat without consuming a large amount of CPU. -- SL6 x86_64 kernel-2.6.32-696.1.1.el6.x86_64.rpm kernel-debug-2.6.32-696.1.1.el6.x86_64.rpm kernel-debug-debuginfo-2.6.32-696.1.1.el6.i686.rpm kernel-debug-debuginfo-2.6.32-696.1.1.el6.x86_64.rpm kernel-debug-devel-2.6.32-696.1.1.el6.i686.rpm kernel-debug-devel-2.6.32-696.1.1.el6.x86_64.rpm kernel-debuginfo-2.6.32-696.1.1.el6.i686.rpm kernel-debuginfo-2.6.32-696.1.1.el6.x86_64.rpm kernel-debuginfo-common-i686-2.6.32-696.1.1.el6.i686.rpm kernel-debuginfo-common-x86_64-2.6.32-696.1.1.el6.x86_64.rpm kernel-devel-2.6.32-696.1.1.el6.x86_64.rpm kernel-headers-2.6.32-696.1.1.el6.x86_64.rpm perf-2.6.32-696.1.1.el6.x86_64.rpm perf-debuginfo-2.6.32-696.1.1.el6.i686.rpm perf-debuginfo-2.6.32-696.1.1.el6.x86_64.rpm python-perf-debuginfo-2.6.32-696.1.1.el6.i686.rpm python-perf-debuginfo-2.6.32-696.1.1.el6.x86_64.rpm python-perf-2.6.32-696.1.1.el6.x86_64.rpm i386 kernel-2.6.32-696.1.1.el6.i686.rpm kernel-debug-2.6.32-696.1.1.el6.i686.rpm kernel-debug-debuginfo-2.6.32-696.1.1.el6.i686.rpm kernel-debug-devel-2.6.32-696.1.1.el6.i686.rpm kernel-debuginfo-2.6.32-696.1.1.el6.i686.rpm kernel-debuginfo-common-i686-2.6.32-696.1.1.el6.i686.rpm kernel-devel-2.6.32-696.1.1.el6.i686.rpm kernel-headers-2.6.32-696.1.1.el6.i686.rpm perf-2.6.32-696.1.1.el6.i686.rpm perf-debuginfo-2.6.32-696.1.1.el6.i686.rpm python-perf-debuginfo-2.6.32-696.1.1.el6.i686.rpm python-perf-2.6.32-696.1.1.el6.i686.rpm noarch kernel-abi-whitelists-2.6.32-696.1.1.el6.noarch.rpm kernel-doc-2.6.32-696.1.1.el6.noarch.rpm kernel-firmware-2.6.32-696.1.1.el6.noarch.rpm - Scientific Linux Development Team .
