Overview
libp2p-core is a rust implementation of libp2p networking stack.
Affected versions of this package are vulnerable to Insufficient Signature Validation. The verify function within ed25519.rs does not properly verify ed25519 signatures. When creating a Ed25519 secret key from a byte slice, combinators were not used resulting in any signature with a correct length being considered valid.
