Red Hat JBoss EAP: CVE-2024-29025: Allocation of Resources Without Limits or Throttling

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. The `HttpPostRequestDecoder` can be tricked to accumulate data. While the decoder can store items on the disk if configured so, there are no limits to the number of fields the form can have, an attacher can send a chunked post consisting of many small fields that will be accumulated in the `bodyListHttpData` list. The decoder cumulates bytes in the `undecodedChunk` buffer until it can decode a field, this field can cumulate data without limits. This vulnerability is fixed in 4.1.108.Final.. A flaw was found in the io.netty:netty-codec-http package. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling issues due to the accumulation of data in the HttpPostRequestDecoder. The decoder cumulates bytes in the undecodedChunk buffer until it can decode a field, allowing data to accumulate without limits. This flaw allows an attacker to cause a denial of service by sending a chunked post consisting of many small fields that will be accumulated in the bodyListHttpData list.
