Описание
If one side of the TLS connection sends multiple key update messages post-handshake in a single record, the connection can deadlock, causing uncontrolled consumption of resources. This can lead to a denial of service. This only affects TLS 1.3.
A flaw was found in the crypto/tls package within the Go (golang) standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock, leading to uncontrolled consumption of resources and ultimately a denial of service (DoS).
Отчет
Important: A flaw in the Go crypto/tls package allows a remote attacker to cause a denial of service in applications using TLS 1.3. By sending multiple key update messages in a single record post-handshake, an attacker can trigger a connection deadlock, leading to uncontrolled resource consumption. This impacts Red Hat products utilizing the affected Go standard library for TLS 1.3 connections.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
