ChunkedStreamSinkConduit write with a buffer array writes too few buffers

    XMLWordPrintable

Details

    Description

      This may manifest in an infinite hot loop as the caller and callee disagree about whether or not data remains in the source buffers.

       

      In this loop, 'length' of the buffers should be written, however length is used as a limit rather than length:
      https://github.com/undertow-io/undertow/blob/e11eba5695c4bf09ed50f298765b876f01f9745c/core/src/main/java/io/undertow/conduits/ChunkedStreamSinkConduit.java#L216-L222

       

       

              for (int i = offset; i < length; ++i) {
            if (srcs[i].hasRemaining()) {
                return write(srcs[i]);
            }
        }

      should be

       

       

              for (int i = offset; i < offset + length; ++i) {
            if (srcs[i].hasRemaining()) {
                return write(srcs[i]);
            }
        }
