TITLE

NetBSD  of   Authentication vulnerability in kernel

DESCRIPTION

An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. NetBSD of An authentication vulnerability exists in the kernel.Service operation interruption (DoS) It may be in a state. This update provides the corresponding updates for the Linux KVM kernel for Ubuntu 21.04. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: Openshift Logging Security Release (5.0.10) Advisory ID: RHSA-2021:5137-01 Product: Red Hat OpenShift Enterprise Advisory URL: https://access.redhat.com/errata/RHSA-2021:5137 Issue date: 2021-12-14 CVE Names: CVE-2018-20673 CVE-2018-25009 CVE-2018-25010 CVE-2018-25012 CVE-2018-25013 CVE-2018-25014 CVE-2019-5827 CVE-2019-13750 CVE-2019-13751 CVE-2019-14615 CVE-2019-17594 CVE-2019-17595 CVE-2019-18218 CVE-2019-19603 CVE-2019-20838 CVE-2020-0427 CVE-2020-10001 CVE-2020-12762 CVE-2020-13435 CVE-2020-14145 CVE-2020-14155 CVE-2020-16135 CVE-2020-17541 CVE-2020-24370 CVE-2020-24502 CVE-2020-24503 CVE-2020-24504 CVE-2020-24586 CVE-2020-24587 CVE-2020-24588 CVE-2020-26139 CVE-2020-26140 CVE-2020-26141 CVE-2020-26143 CVE-2020-26144 CVE-2020-26145 CVE-2020-26146 CVE-2020-26147 CVE-2020-27777 CVE-2020-29368 CVE-2020-29660 CVE-2020-35448 CVE-2020-35521 CVE-2020-35522 CVE-2020-35523 CVE-2020-35524 CVE-2020-36158 CVE-2020-36312 CVE-2020-36330 CVE-2020-36331 CVE-2020-36332 CVE-2020-36386 CVE-2021-0129 CVE-2021-3200 CVE-2021-3348 CVE-2021-3426 CVE-2021-3445 CVE-2021-3481 CVE-2021-3487 CVE-2021-3489 CVE-2021-3564 CVE-2021-3572 CVE-2021-3573 CVE-2021-3580 CVE-2021-3600 CVE-2021-3635 CVE-2021-3659 CVE-2021-3679 CVE-2021-3712 CVE-2021-3732 CVE-2021-3778 CVE-2021-3796 CVE-2021-3800 CVE-2021-20194 CVE-2021-20197 CVE-2021-20231 CVE-2021-20232 CVE-2021-20239 CVE-2021-20266 CVE-2021-20284 CVE-2021-22876 CVE-2021-22898 CVE-2021-22925 CVE-2021-23133 CVE-2021-23840 CVE-2021-23841 CVE-2021-27645 CVE-2021-28153 CVE-2021-28950 CVE-2021-28971 CVE-2021-29155 CVE-2021-29646 CVE-2021-29650 CVE-2021-31440 CVE-2021-31535 CVE-2021-31829 CVE-2021-31916 CVE-2021-33033 CVE-2021-33200 CVE-2021-33560 CVE-2021-33574 CVE-2021-35942 CVE-2021-36084 CVE-2021-36085 CVE-2021-36086 CVE-2021-36087 CVE-2021-42574 CVE-2021-43527 CVE-2021-44228 ==================================================================== 1.

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.
