security advisorydenial of servicearbitrary code executionUbuntu 21.10 Security Advisory USN-5162-1: Kernel Issues Found
Several security issues were fixed in the Linux kernel.. =========================================================================Ubuntu Security Notice USN-5162-1 November 30, 2021 linux, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-oem-5.13, linux-oracle, linux-raspi vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 21.10 - Ubuntu 20.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-kvm: Linux kernel for cloud environments - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems - linux-oem-5.13: Linux kernel for OEM systems Details: Ilja Van Sprundel discovered that the SCTP implementation in the Linux kernel did not properly perform size validations on incoming packets in some situations. An attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2021-3655) It was discovered that the AMD Cryptographic Coprocessor (CCP) driver in the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2021-3744, CVE-2021-3764) It was discovered that the Aspeed Low Pin Count (LPC) Bus Controller implementation in the Linux kernel did not properly perform boundary checks in some situations, allowing out-of-bounds write access. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. In Ubuntu, this issue only affected systems running armhf kernels. (CVE-2021-42252) Jann Horn discovered that the SELinux subsystem in the Linux kernel did not properly handle subjective credentials for tasks insome situations. On systems where SELinux has been enabled, a local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2021-43057) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 21.10: linux-image-5.13.0-1006-kvm 5.13.0-1006.6 linux-image-5.13.0-1007-aws 5.13.0-1007.8 linux-image-5.13.0-1007-gcp 5.13.0-1007.8 linux-image-5.13.0-1008-azure 5.13.0-1008.9 linux-image-5.13.0-1010-oracle 5.13.0-1010.12 linux-image-5.13.0-1011-raspi 5.13.0-1011.13 linux-image-5.13.0-1011-raspi-nolpae 5.13.0-1011.13 linux-image-5.13.0-22-generic 5.13.0-22.22 linux-image-5.13.0-22-generic-64k 5.13.0-22.22 linux-image-5.13.0-22-generic-lpae 5.13.0-22.22 linux-image-5.13.0-22-lowlatency 5.13.0-22.22 linux-image-aws 5.13.0.1007.9 linux-image-azure 5.13.0.1008.9 linux-image-gcp 5.13.0.1007.8 linux-image-generic 5.13.0.22.33 linux-image-generic-64k 5.13.0.22.33 linux-image-generic-lpae 5.13.0.22.33 linux-image-gke 5.13.0.1007.8 linux-image-kvm 5.13.0.1006.6 linux-image-lowlatency 5.13.0.22.33 linux-image-oem-20.04 5.13.0.22.33 linux-image-oracle 5.13.0.1010.12 linux-image-raspi 5.13.0.1011.17 linux-image-raspi-nolpae 5.13.0.1011.17 linux-image-virtual 5.13.0.22.33 Ubuntu 20.04 LTS: linux-image-5.13.0-1020-oem 5.13.0-1020.24 linux-image-oem-20.04c 5.13.0.1020.24 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 advisoryred hatbug fixRed Hat 6.4: RHSA-2015:0043-01 Important DoS from SCTP Access
Updated kernel packages that fix three security issues and several bugs are now available for Red Hat Enterprise Linux 6.4 Extended Update Support. Red Hat Product Security has rated this update as having Important security [More...]. ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2015:0043-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2015:0043.html Issue date: 2015-01-13 CVE Names: CVE-2014-3673 CVE-2014-3687 CVE-2014-3688 ==================================================================== 1. Summary: Updated kernel packages that fix three security issues and several bugs are now available for Red Hat Enterprise Linux 6.4 Extended Update Support. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Compute Node Optional EUS (v. 6.4) - x86_64 Red Hat Enterprise Linux HPC Node EUS (v. 6.4) - noarch, x86_64 Red Hat Enterprise Linux Server EUS (v. 6.4) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 6.4) - i386, ppc64, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel's SCTP implementation handled malformed or duplicate Address Configuration Change Chunks (ASCONF). A remote attacker could use either of these flaws to crash the system. (CVE-2014-3673, CVE-2014-3687, Important) * A flaw was found in the way the Linux kernel's SCTP implementation handled the association's output queue. A remote attacker could send specially crafted packets that would cause the systemto use an excessive amount of memory, leading to a denial of service. (CVE-2014-3688, Important) The CVE-2014-3673 issue was discovered by Liu Wei of Red Hat. This update also fixes the following bugs: * When the Baseboard Management Controller (BMC) was reset, the settings for the ipmi_watchdog driver were not restored correctly causing error 80 to be returned. With this update, Intelligent Platform Management Interface (IPMI) is reset as expected in the described situation, and the error is no longer returned. (BZ#1109268) * Under certain conditions, XFS log flushes could exceed the kernel thread stack size. As a consequence, a kernel panic occurred on systems using XFS file systems. This update provides a patch that moves this code path to a work queue, and therefore the stack overflow no longer occurs. (BZ#1154086) * Due to a race condition, an attempt to unmount an XFS file system using the umount command could fail, causing the system to become unresponsive. The underlying source code has been modified to fix this bug, and the system no longer hangs in the described situation. (BZ#1158320) * Previously, the printk_ratelimited() function printed messages which were supposed to be suppressed, and failed to print messages that were supposed to be printed. This was caused by the incorrect usage of the __ratelimit() function. This bug has been fixed with this update, and now printk_ratelimit() behaves as expected. (BZ#1169401) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that willremove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system. 5. Bugs fixed (https://bugzilla.redhat.com/): 1147850 - CVE-2014-3673 kernel: sctp: skb_over_panic when receiving malformed ASCONF chunks 1155731 - CVE-2014-3687 kernel: net: sctp: fix panic on duplicate ASCONF chunks 1155745 - CVE-2014-3688 kernel: net: sctp: remote memory pressure from excessive queueing 6.
