In versions prior 0.11.3 it's possible to make
from_slice panic by feeding it certain malformed input.
It's never documented that
from_bytes which wraps it) can panic, and its' return type (
Result<Self, DecodeError>) suggests otherwise.
from_bytes is frequently used in networking code (for example in rust-libp2p) and is being called with unsanitized data from untrusted sources.
This can allow attackers to cause DoS by causing an unexpected
panic in the network client's code.
