Versiosn prior to2.2.0 have a protocol compliance vulnerability. The library allowed post-quantum handshake patterns that violated the PSK validity rule (Noise Protocol Framework Section 9.3). This could allow PSK-derived keys to be used for encryption without proper randomization by self-chosen ephemeral randomness, weakening security guarantees and potentially allowing catastrophic key reuse. Affected default patterns include `noise_pqkk_psk0`, `noise_pqkn_psk0`, `noise_pqnk_psk0`, `noise_pqnn_psk0``, and some hybrid variants. Users of these patterns may have been using handshakes that do not meet the intended security properties. The issue is fully patched and released in Clatter v2.2.0. The fixed version includes runtime checks to detect offending handshake patterns. As a workaround, avoid using offending `*_psk0` variants of post-quantum patterns. Review custom handshake patterns carefully."}, {"lang": "es", "value": "Clatter es una implementaci\u00f3n pura de Rust, compatible con no_std, del framework del protocolo Noise con soporte post-cu\u00e1ntico. Las versiones anteriores a 2.2.0 tienen una vulnerabilidad de cumplimiento del protocolo. La librer\u00eda permit\u00eda patrones de handshake post-cu\u00e1nticos que violaban la regla de validez de PSK (Framework del Protocolo Noise Secci\u00f3n 9.3). Esto podr\u00eda permitir que las claves derivadas de PSK se usaran para cifrado sin una aleatorizaci\u00f3n adecuada por aleatoriedad ef\u00edmera auto-elegida, debilitando las garant\u00edas de seguridad y potencialmente permitiendo la reutilizaci\u00f3n catastr\u00f3fica de claves. Los patrones predeterminados afectados incluyen 'noise_pqkk_psk0', 'noise_pqkn_psk0', 'noise_pqnk_psk0', 'noise_pqnn_psk0', y algunas variantes h\u00edbridas. Los usuarios de estos patrones pueden haber estado utilizando handshakes que no cumplen con las propiedades de seguridad previstas. El problema est\u00e1 completamente parcheado y lanzado en Clatter v2.2.0. La versi\u00f3n corregida incluye comprobaciones en tiempo de ejecuci\u00f3n para detectar patrones de handshake ofensivos.
