Description
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.
