### Impact Unintended permanent chain split affecting greater than or equal to 25% of the network, requiring hard fork (network partition requiring hard fork) Lodestar does not verify checksum in snappy framing uncompressed chunks. ### Vulnerability Details In Req/Resp protocol the messages are encoded by using ssz_snappy encoding, which is a snappy framing compression over ssz encoded message. In snappy framing format there are uncompressed chunks, each such chunk is prefixed with a checksum. Let's see how golang implementation parses such chunks - https://github.com/golang/snappy/blob/master/decode.go#L176 ``` case chunkTypeUncompressedData: // Section 4.3. Uncompressed data (chunk type 0x01). if chunkLen < checksumSize { r.err = ErrCorrupt return r.err } buf := r.buf[:checksumSize] if !r.readFull(buf, false) { return r.err } checksum := uint32(buf[0]) | uint32(buf[1])<<8 | uint32(buf[2])<<16 | uint32(buf[3])<<24 // Read directly into r.decod...
