What is CVE-2020-35864?

A vulnerability in the flatbuffers crate for Rust has been identified that permits the transmutation of values without the use of unsafe blocks in the 'read_scalar' and 'read_scalar_at' functions. This could potentially allow for unsafe type conversions in applications, leading to unexpected behavior and security implications. Developers relying on the flatbuffers crate should review their code to ensure no unintended transmutations occur, and adhere to best practices for type safety in Rust.
