Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, the Bzip2Decoder handler in Netty's compression codec pipeline is vulnerable to a denial-of-service attack through a malformed bzip2 stream that permanently captures the event-loop thread in an infinite loop. The vulnerability exists in the run-length encoding (RLE) state machine within [Bzip2BlockDecompressor.read()]. This issue has been fixed in versions 4.1.136.Final and 4.2.16.Final.

(Netty is an asynchronous, event-driven network application framework. ...)
A flaw was found in the netty-codec-compression component of Netty. This vulnerability, caused by a logic error in the bzip2 decoder, allows a remote attacker to send specially crafted bzip2-compressed data. Processing this malformed data can trigger an infinite loop, causing the decoder thread to consume excessive CPU resources. This leads to a denial of service (DoS), requiring manual intervention to restore service.
