Improper validation of length fields in the Apache IoTDB RPC service may allow a remote unauthenticated attacker to cause a denial of service. By sending a crafted malformed Thrift frame, an attacker can cause IoTDB to allocate an excessive amount of memory and crash with an OutOfMemoryError.
This issue affects Apache IoTDB: before 1.3.8, from 2.0.0 before 2.0.9.
Users are recommended to upgrade to version 2.0.10, which fixes the issue.
