Description

A flaw was found in Netty, an asynchronous, event-driven network application framework. A remote attacker could exploit this vulnerability by sending a specific sequence of HTTP responses (103, followed by a 200 with a GET body, then another 200 for a HEAD request) when the client pipelines GET then HEAD requests. This can cause the HttpClientCodec to incorrectly pair responses, leading to subsequent HTTP responses being parsed from the wrong offset. This issue may result in information disclosure or other data integrity problems due to misinterpretation of network traffic.
