Summary
Deserialization functions pass uninitialized memory to user-provided Read
Details

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.
