Description d'origine
La description telle que publiée par la source (souvent en anglais).
libcurl's TFTP state machine fails to validate state transitions against the requested transfer direction, accepting opening server responses for both reads and writes interchangeably. A malicious TFTP server can respond to a download request in a way that forces the client into transmit mode, prompting libcurl to consume and transmit data from the handle's persistent CURLOPT_READDATA pointer - including data remaining from unrelated prior operations, such as an HTTP POST request executed on a reused handle.
