优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
漏洞描述 在 Netty 消息处理管线中，Worker 的 Netty 消息解码器被安装在 SASL 认证处理器之前，因此在任何认证发生之前就会处理接收到的帧。该解码器根据帧中携带的长度字段来分配缓冲区，因此来自未认证对等方的单个帧，如果该对等方能够访问 Worker 插槽端口，就可能触发大内存分配。 默认为 ，且解码器在任何情况下都运行在强制认证的处理程序之前，因此无需凭证即可触发。攻击者只需具备到 Worker 端口的 TCP 可达性即可利用此漏洞。 在默认 768 MB Worker 堆内存配置下，单个帧的影

Vulnerability Title
Apache Storm Worker: Unauthenticated Remote Memory Exhaustion in the Worker Messaging Decoder
来源: CVE Program / CVE List V5
Vulnerability Description
Description
The worker's Netty message decoder is installed ahead of the SASL authentication handlers in the pipeline
and acts on frames before any authentication has taken place. It allocated buffers sized from a
length field carried in the frame, so a single frame from an unauthenticated peer able to reach a worker
slot port could drive a large allocation.
`storm.messaging.netty.authentication` defaults to false, and the decoder runs before the handler that
enforces it in any case, so no credentials are required. The attacker needs only TCP reachability to a
worker port.
The effect of a single frame at the default 768 MB worker heap has not been measured to distinguish
sustained worker loss from transient garbage-collection pressure. The severity assigned to this advisory
reflects the more conservative reading; consumers who require a precise figure should test against their own
worker heap configuration.
Mitigation
Upgrade to 3.1.0, where frames are decoded only after the handshake completes.
Users who cannot upgrade immediately should ensure that worker slot ports are reachable only from within the
cluster, as the security model already recommends, and should enable
`storm.messaging.netty.authentication` where the deployment permits it.
