CyberRota Analysis
AI-GeneratedThe vulnerability exists in the StompSubframeDecoder of the Netty framework, where it fails to limit the total number of headers or their cumulative size per frame, potentially leading to a denial of service (DoS) due to an OutOfMemoryError. This issue affects any servers utilizing STOMP endpoints with versions prior to 4.1.136.Final and 4.2.16.Final. Organizations using these affected versions should prioritize updating to the fixed versions to mitigate the risk of service disruption.

Original NVD Description
Netty is a network application framework for development of protocol servers and clients. Prior to 4.1.136.Final and 4.2.16.Final, io.netty.handler.codec.stomp.StompSubframeDecoder fails to limit the total number of headers or their cumulative size per frame, and the maxLineLength parameter only restricts individual header lines. An attacker can send a large number of short headers that are accumulated in memory inside DefaultStompHeadersSubframe until the JVM throws an OutOfMemoryError, causing denial of service for servers exposing a STOMP endpoint based on StompSubframeDecoder. This issue is fixed in versions 4.1.136.Final and 4.2.16.Final.
