CVE-2020-36448 — Vulnerability in cache — CVE Details

HIGH

Cache<K>: Send/Sync impls needs trait bounds on `K`

Published November 24, 2020Updated November 8, 2023Source: osv

Summary

Affected versions of this crate unconditionally implement Send/Sync for `Cache<K>`. This allows users to insert `K` that is not Send or not Sync. This allows users to create data races by using non-Send types like `Arc<Cell<T>>` or `Rc<T>` as `K` in `Cache<K>`. It is also possible to create data races by using types like `Cell<T>` or `RefCell<T>` (types that are `Send` but not `Sync`). Such data races can lead to memory corruption.
