Nervos CKB P2P DoS Attacks

The P2P protocols lack of rate limit. For example, in relay protocol, when a node receives a broadcasted txhashes, it will mark it in memory to avoid duplicated requests. code → . It is easy to establish a DoS attach by generating random tx hashes. Impact It affects all nodes connected to the P2P...

Nervos CKB Unaligned Pointer Dereference

via [email protected] There are multiple type conversions in ckb that unsafely cast between byte pointers and other types of pointers. This results in unaligned pointers, which are not allowed by the Rust language, and are considered undefined behavior, meaning that the compiler is free to do...
