GHSA-m325-rxjv-pwph: Deserialization functions pass uninitialized memory to user-provided Read

June 17, 2022 (updated June 13, 2023)

Affected versions of this crate passed an uninitialized buffer to a user-provided Read instance in:

deserialize_binary
deserialize_string
deserialize_extension_others
deserialize_string_primitive

This can result in safe Read implementations reading from the uninitialized buffer leading to undefined behavior.
