Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

A flaw in Netty's WebSocketServerExtensionHandler allows a remote, unauthenticated attacker to cause unbounded per-connection queue growth, leading to a Denial of Service. The attacker can exploit this using HTTP/1.1 pipelining. Affected products include Red Hat builds of various applications.

Original source description

Read the full publisher description

A flaw was found in Netty's WebSocketServerExtensionHandler. A remote, unauthenticated attacker can exploit this vulnerability by using HTTP/1.1 pipelining to send requests faster than the application can respond. This leads to an unbounded growth of a per-connection queue, consuming excessive memory. Eventually, this can cause the Java Virtual Machine (JVM) to exhaust its heap, resulting in a Denial of Service (DoS) for the affected server.
