Description

Apache Fluss versions prior to 0.9.1 configure the Netty LengthFieldBasedFrameDecoder with Integer.MAX_VALUE as the maximum frame length, allowing unauthenticated remote attackers to exhaust JVM heap memory on TabletServer and CoordinatorServer by sending specially crafted frame headers, resulting in denial of service.<br /> <br /> This issue affects Apache Fluss (incubating): 0.8.0 and 0.9.0.<br /> <br /> Users are recommended to upgrade to version 0.9.1, which fixes the issue.
