Vulnerability from variot
A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact. nginx The resolver contains a vulnerability in determining boundary conditions.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Nginx is a lightweight web server/reverse proxy server and email (IMAP/POP3) proxy server of Nginx Company in the United States. Affected products and versions are as follows: nginx: 0.6.18, 0.6.19 0.6.20, 0.6.21, 0.6.22 0.6.23, 0.6.24, 0.6.25, 0.6.26, 0.6.27, 0.6. A flaw was found in nginx. An off-by-one error while processing DNS responses allows a network malicious user to write a dot character out of bounds in a heap allocated buffer which can allow overwriting the least significant byte of next heap chunk metadata likely leading to a remote code execution in certain circumstances. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2021-23017). - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 202105-38

- 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.

"data": "A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact. nginx The resolver contains a vulnerability in determining boundary conditions.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Nginx is a lightweight web server/reverse proxy server and email (IMAP/POP3) proxy server of Nginx Company in the United States. Affected products and versions are as follows: nginx: 0.6.18, 0.6.19 0.6.20, 0.6.21, 0.6.22 0.6.23, 0.6.24, 0.6.25, 0.6.26, 0.6.27, 0.6. A flaw was found in nginx. An off-by-one error while processing DNS responses allows a network malicious user to write a dot character out of bounds in a heap allocated buffer which can allow overwriting the least significant byte of next heap chunk metadata likely leading to a remote code execution in certain circumstances. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Summary:\n\nRed Hat Advanced Cluster Management for Kubernetes 2.3.3 General\nAvailability release images, which fix bugs, provide security fixes, and\nupdate container images. Description:\n\nRed Hat Advanced Cluster Management for Kubernetes 2.3.3 images\n\nRed Hat Advanced Cluster Management for Kubernetes provides the\ncapabilities to address common challenges that administrators and site\nreliability engineers face as they work across a range of public and\nprivate cloud environments. Clusters and applications are all visible and\nmanaged from a single console\u2014with\nsecurity policy built in.
