An issue was discovered in the convec crate through 2020-11-24 for Rust. There are unconditional implementations of Send and Sync for ConVec<T>.

GHSA-rpxm-vmr7-5f5f — Data races in convec

Affected: crates.io: convec

Affected versions of this crate unconditionally implement Send/Sync for `ConVec<T>`. This allows users to insert `T` that is not Send or not Sync.

This allows users to create data races by using non-Send types like `Arc<Cell<_>>` or `Rc<_>` as `T` in `ConVec<T>`. It is also possible to create data races by using types like `Cell<_>` or `RefCell<_>` as `T` (types that are `Send` but not `Sync`). Such data races can lead to memory corruption.
