Advisories for Cargo/Generator package

An issue was discovered in the generator crate before 0.6.18 for Rust. Uninitialized memory is used by Scope, done, and yield_ during API calls.

The Generator type is an iterable which uses a generator function that yields values. In affected versions of the crate, the provided function yielding values had no Send bounds despite the Generator itself implementing Send. The generator function lacking a Send bound means that types that are dangerous to send across threads such as Rc could be sent as part of a generator, potentially leading to data races.
