JSON

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.

Mitigation

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
