CyberRota Analysis
AI-GeneratedA vulnerability in Netty allows an attacker to initiate an unlimited number of concurrent streams through the SpdySessionHandler, leading to unbounded heap and direct memory allocation. This can result in a denial of service due to a JVM OutOfMemoryError. Organizations using Netty, particularly those implementing SPDY connections, should prioritize addressing this issue to prevent potential service disruptions.

Original NVD Description
A flaw was found in Netty. SpdySessionHandler accepts an unlimited number of concurrent remote-initiated streams because localConcurrentStreams defaults to Integer.MAX_VALUE and the handler provides no API to change it. A remote peer can open a SPDY connection and send a large number of SYN_STREAM frames with FLAG_FIN=0, causing unbounded heap and direct memory allocation that can lead to JVM OutOfMemoryError and a denial of service.
