Name of the Vulnerable Software and Affected Versions Dragonfly versions prior to 2.1.0

Description The processPieceFromSource method in Dragonfly does not correctly update the usedTraffic field within the Task structure due to the use of an uninitialized variable (n) instead of result.Size when calling the AddTraffic method.
