Affected versions of this crate did not properly verify ed25519 signatures. Any signature with a correct length was considered valid.
This allows an attacker to impersonate any node identity.

tokio
: Data race when sending and receiving after closing a `oneshot` channelIf a tokio::sync::oneshot
channel is closed (via the
oneshot::Receiver::close
method), a data race may occur if the
oneshot::Sender::send
method is called while the corresponding
oneshot::Receiver
is await
ed or calling try_recv
.
When these methods are called concurrently on a closed channel, the two halves of the channel can concurrently access a shared memory location, resulting in a data race. This has been observed to cause memory corruption.
Note that the race only occurs when both halves of the channel are used
after the Receiver
half has called close
. Code where close
is not used, or where the
Receiver
is not await
ed and try_recv
is not called after calling close
,
is not affected.
See tokio#4225 for more details.
