Vulnerability Title
Netty SPDY zlib header block continues decoded expansion after maxHeaderSize truncation
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, Netty SPDY header decoding continues inflating zlib-compressed header blocks after the raw header parser has exceeded `maxHeaderSize` and marked the frame truncated in `SpdyFrameCodec`, allowing a remote peer to send a small compressed `HEADERS` block that expands into much larger raw header data and causes compression-amplified CPU and allocation churn. 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SPDY标头解码在原始标头解析器超过maxHeaderSize后继续解压zlib压缩标头块,允许远程对等端发送小型压缩HEADERS块,扩展成更大原始标头数据,导致CPU和内存分配大量消耗。
