Vulnerability Title
Netty: Denial of Service via Unbounded Headers in StompSubframeDecoder
Vulnerability 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.

Vulnerability Title
Netty 资源管理错误漏洞
Vulnerability Description
Netty是Netty团队开源的一款非阻塞I/O客户端-服务器框架,它主要用于开发Java网络应用程序,如协议服务器和客户端等。 Netty 4.1.136.Final之前版本和4.2.16.Final之前版本存在资源管理错误漏洞,该漏洞源于StompSubframeDecoder未限制每帧的标头总数或其累积大小,且maxLineLength参数仅限制单个标头行,可能导致攻击者发送大量短标头,在内存中累积直至JVM抛出OutOfMemoryError,从而对基于StompSubframeDecoder暴露
