0.1.0--0.3.1 are affected versions of the futures had an unsound Sync implementation on the FuturesUnordered structure, which used a Cell for interior mutablity without any code to handle synchronized access to the underlying task list’s length and head safely. This could of lead to data corruption since two threads modifying the list at once could see incorrect values due to the lack of access synchronization. The issue was fixed in 0.3.2 by adding access synchronization code around insertion of tasks into the list.
