CVE-2020-35886
Multiple security issues including data race, buffer overflow, and uninitialized memory drop in arr
Impact
arr crate contains multiple security issues. Specifically, 1. It incorrectly implements Sync/Send bounds, which allows to smuggle non-Sync/Send types across the thread boundary. 2. Index and IndexMut implementation does not check the array bound. 3. Array::new_from_template() drops uninitialized memory.
