Malicious raw key triggers out of range panic in Go standard library Fixed 3 Key with empty seed will trigger panic in Go standard library Fixed Index out of range in raft log reading OSS-Fuzz bug tracker: Data), err.Error()) return false } return updated } Figure 1.1: Proof of concept payload to trigger issue ADA-DAP-FUZZ-1 Malicious raw key triggers out of range panic in Go standard library OSS-Fuzz Description A fuzzer testing kit/crypto found that malicious raw bytes can be parsed into a key that will trigger a panic in the Go standard library, when the key gets serialized. This is illustrated with the below
