      Description

      Operations: During Apache Thrift integration testing, I developed a calculator application with a client and a server. The client sent a computational command and get the result from the server. After I applied dynamic taint analyzer (distTaint), I found bugs from taint paths finally.

      The source: org.apache.thrift.transport.TIOStreamTransport:
      public int read(byte[] buf, int off, int len) throws TTransportException {
      if (inputStream_ == null)

      { throw new TTransportException(TTransportException.NOT_OPEN, "Cannot read from null inputStream"); }

      int bytesRead;
      ......
      bytesRead = inputStream_.read(buf, off, len);
      ......
      }

      The sink: org.apache.thrift.transport.TTransport,
      public int readAll(byte[] buf, int off, int len)
      throws TTransportException {
      ......
      if (ret <= 0)

      { throw new TTransportException( "Cannot read. Remote side has closed. Tried to read " + len + " bytes, but only got " + got + " bytes. (This is often indicative of an internal error on the server side. Please check your server logs.)"); }

      ......
      }
      Sensitive information about expected and actual reading lengths (len, got) is leaked.
      The tainted path:
      org.apache.thrift.transport.TIOStreamTransport -->
      org.apache.thrift.transport.TTransport

      I am going to submit a CVE, so please confirm this is not a true positive.
