0 An integer underflow vulnerability exists in Apache bRPC versions before 1.18.0 in the mcpack2pb component. This flaw allows remote attackers to crash a bRPC server by sending a specially crafted request with a string field having a zero value_size. The vulnerability arises because the UnparsedValue::as_string() function subtracts one from the value_size without validating it, causing an underflow and an uncaught exception that aborts the process. Default server configurations are typically not affected, but certain deployment patterns using nshead frames with the ubrpc mcpack2 adaptor are vulnerable.
