> Key: NET-414
> URL: https://issues.apache.org/jira/browse/NET-414
> Project: Commons Net
> Issue Type: Bug
> Components: TFTP
> Affects Versions: 2.2, 3.0
> Environment: Java 1.6 Patch 20
> Reporter: Chuck Wolber
> Priority: Minor
> Fix For: 3.6
>
>
> When a TFTP request response arrives that incorrectly specifies its source
> port as the control port, the request should be rejected with an error code 5
> (TFTPErrorPacket.UNKNOWN_TID) and suggested text "INCORRECT SOURCE PORT".
> This can happen when an incorrectly written TFTP server replies to a request
> from a control socket instead of building a new socket that attaches to an
> ephemeral port.
> Note 1: The expected response from a read request is a DATA packet. The
> expected response from a write request is an ACK packet.
> Note 2: The control port is implementation specific and not always port 69
> (as defined by IANA).
