Summary

futures_task::waker may cause a use-after-free if used on a type that isn't 'static

Details

Affected versions of the crate did not properly implement a 'static lifetime bound on the waker function. This resulted in a use-after-free if Waker::wake() is called after original data had been dropped.

The flaw was corrected by adding 'static lifetime bound to the data waker takes.
