TITLE

Linux Kernel  Buffer Error Vulnerability

DESCRIPTION

An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation. Linux Kernel Is vulnerable to a buffer error.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Arch Linux is an application system of Arch open source. A lightweight and flexible Linux® distribution that tries to keep it simple. Summary: Red Hat Advanced Cluster Management for Kubernetes 2.3.3 General Availability release images, which fix bugs, provide security fixes, and update container images. Description: Red Hat Advanced Cluster Management for Kubernetes 2.3.3 images Red Hat Advanced Cluster Management for Kubernetes provides the capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of public and private cloud environments. Clusters and applications are all visible and managed from a single console—with security policy built in. See the following Release Notes documentation, which will be updated shortly for this release, for additional details about this release: https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_mana gement_for_kubernetes/2.3/html/release_notes/ Note: Because Red Hat OpenShift Container Platform version 4.9 was just released, the functional testing of the compatibility between Red Hat Advanced Cluster Management 2.3.3 and Red Hat OpenShift Container Platform version 4.9 is still in progress. Security fixes: * nginx: Off-by-one in ngx_resolver_copy() when labels are followed by a pointer to a root domain name (CVE-2021-23017) * redis: Lua scripts can overflow the heap-based Lua stack (CVE-2021-32626) * redis: Integer overflow issue with Streams (CVE-2021-32627) * redis: Integer overflow bug in the ziplist data structure (CVE-2021-32628) * redis: Integer overflow issue with intsets (CVE-2021-32687) * redis: Integer overflow issue with strings (CVE-2021-41099) * redis: Out of bounds read in lua debugger protocol parser (CVE-2021-32672) * redis: Denial of service via Redis Standard Protocol (RESP) request (CVE-2021-32675) * helm: information disclosure vulnerability (CVE-2021-32690) Bug fixes: * KUBE-API: Support move agent to different cluster in the same namespace (BZ# 1977358) * Add columns to the Agent CRD list (BZ# 1977398) * ClusterDeployment controller watches all Secrets from all namespaces (BZ# 1986081) * RHACM 2.3.3 images (BZ# 1999365) * Workaround for Network Manager not supporting nmconnections priority (BZ# 2001294) * create cluster page empty in Safary Browser (BZ# 2002280) * Compliance state doesn't get updated after fixing the issue causing initially the policy not being able to update the managed object (BZ# 2002667) * Overview page displays VMware based managed cluster as other (BZ# 2004188) 3.

Bug Fix(es): * Rebase package(s) to version: 1.2.23 Highlights, important fixes, or notable enhancements: * imgbase should not copy the selinux binary policy file (BZ# 1979624) (BZ#1989397) * RHV-H has been rebased on Red Hat Enterprise Linux 8.4 Batch #2. (BZ#1975177) 4. 7) - ppc64le, x86_64 3. Description: This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. ========================================================================== Ubuntu Security Notice USN-5094-1 September 29, 2021 linux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-dell300x, linux-gcp, linux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle, linux-snapdragon vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 18.04 LTS - Ubuntu 16.04 ESM - Ubuntu 14.04 ESM Summary: Several security issues were fixed in the Linux kernel. An attacker who could start and control a VM could possibly use this to expose sensitive information or execute arbitrary code. A privileged attacker could use this to cause a denial of service. (CVE-2021-3679) Alois Wohlschlager discovered that the overlay file system in the Linux kernel did not restrict private clones in some situations. An attacker could use this to expose sensitive information. (CVE-2021-3732) Alexey Kardashevskiy discovered that the KVM implementation for PowerPC systems in the Linux kernel did not properly validate RTAS arguments in some situations. An attacker in a guest vm could use this to cause a denial of service (host OS crash) or possibly execute arbitrary code. (CVE-2021-37576) It was discovered that the MAX-3421 host USB device driver in the Linux kernel did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2021-38204) It was discovered that the Xilinx 10/100 Ethernet Lite device driver in the Linux kernel could report pointer addresses in some situations. An attacker could use this information to ease the exploitation of another vulnerability. (CVE-2021-38205) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-4.15.0-1028-dell300x 4.15.0-1028.33 linux-image-4.15.0-1081-oracle 4.15.0-1081.89 linux-image-4.15.0-1100-kvm 4.15.0-1100.102 linux-image-4.15.0-1109-gcp 4.15.0-1109.123 linux-image-4.15.0-1112-aws 4.15.0-1112.119 linux-image-4.15.0-1113-snapdragon 4.15.0-1113.122 linux-image-4.15.0-1124-azure 4.15.0-1124.137 linux-image-4.15.0-159-generic 4.15.0-159.167 linux-image-4.15.0-159-generic-lpae 4.15.0-159.167 linux-image-4.15.0-159-lowlatency 4.15.0-159.167 linux-image-aws-lts-18.04 4.15.0.1112.115 linux-image-azure-lts-18.04 4.15.0.1124.97 linux-image-dell300x 4.15.0.1028.30 linux-image-gcp-lts-18.04 4.15.0.1109.128 linux-image-generic 4.15.0.159.148 linux-image-generic-lpae 4.15.0.159.148 linux-image-kvm 4.15.0.1100.96 linux-image-lowlatency 4.15.0.159.148 linux-image-oracle-lts-18.04 4.15.0.1081.91 linux-image-snapdragon 4.15.0.1113.116 linux-image-virtual 4.15.0.159.148 Ubuntu 16.04 ESM: linux-image-4.15.0-1081-oracle 4.15.0-1081.89~16.04.1 linux-image-4.15.0-1109-gcp 4.15.0-1109.123~16.04.1 linux-image-4.15.0-1112-aws 4.15.0-1112.119~16.04.1 linux-image-4.15.0-1124-azure 4.15.0-1124.137~16.04.1 linux-image-4.15.0-159-generic 4.15.0-159.167~16.04.1 linux-image-4.15.0-159-lowlatency 4.15.0-159.167~16.04.1 linux-image-aws-hwe 4.15.0.1112.103 linux-image-azure 4.15.0.1124.115 linux-image-gcp 4.15.0.1109.110 linux-image-generic-hwe-16.04 4.15.0.159.152 linux-image-gke 4.15.0.1109.110 linux-image-lowlatency-hwe-16.04 4.15.0.159.152 linux-image-oem 4.15.0.159.152 linux-image-oracle 4.15.0.1081.69 linux-image-virtual-hwe-16.04 4.15.0.159.152 Ubuntu 14.04 ESM: linux-image-4.15.0-1124-azure 4.15.0-1124.137~14.04.1 linux-image-azure 4.15.0.1124.97 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. 8.2) - aarch64, noarch, ppc64le, s390x, x86_64 3.
