CVE-2021-34558

El paquete crypto/tls de Go versiones hasta 1.16.5, no afirma apropiadamente que el tipo de clave pública en un certificado X.509 coincida con el tipo esperado cuando se hace un intercambio de claves basado en RSA, permitiendo a un servidor TLS malicioso causar el pánico en un cliente TLS

A flaw was found in golang. A panic can be triggered by an attacker in a privileged network position without access to the server certificate's private key, as long as a trusted ECDSA or Ed25519 certificate for the server exists (or can be issued), or the client is configured with Config.InsecureSkipVerify. Clients that disable all TLS_RSA cipher suites (that is, TLS 1.0–1.2 cipher suites without ECDHE), as well as TLS 1.3-only clients, are unaffected.

New Features The release of RHACS 3.64 provides the following new features: 1. You can now use deployment and namespace annotations to define where RHACS sends the violation notifications when configuring your notifiers such as Slack, Microsoft Teams, Email, and others. 2. The Red Hat Advanced Cluster Security Operator now supports the ability to allow users to set the enforcement behavior of the admission controller as part of their custom resource. 3. RHACS now supports kernel modules for Ubuntu 16.04 LTS with extended security maintenance.
