CVE-2026-24785

Estado: AnalizadaAlta (8)—

Clatter is a no_std compatible, pure Rust implementation of the Noise protocol framework with post-quantum support. 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.

      "value": "Clatter es una implementación pura de Rust, compatible con no_std, del framework del protocolo Noise con soporte post-cuántico. Las versiones anteriores a 2.2.0 tienen una vulnerabilidad de cumplimiento del protocolo. La librería permitía patrones de handshake post-cuánticos que violaban la regla de validez de PSK (Framework del Protocolo Noise Sección 9.3). Esto podría permitir que las claves derivadas de PSK se usaran para cifrado sin una aleatorización adecuada por aleatoriedad efímera auto-elegida, debilitando las garantías de seguridad y potencialmente permitiendo la reutilización catastrófica de claves. Los patrones predeterminados afectados incluyen 'noise_pqkk_psk0', 'noise_pqkn_psk0', 'noise_pqnk_psk0', 'noise_pqnn_psk0', y algunas variantes híbridas. Los usuarios de estos patrones pueden haber estado utilizando handshakes que no cumplen con las propiedades de seguridad previstas. El problema está completamente parcheado y lanzado en Clatter v2.2.0. La versión corregida incluye comprobaciones en tiempo de ejecución para detectar patrones de handshake ofensivos. Como solución alternativa, evite usar las variantes ofensivas '*_psk0' de patrones post-cuánticos. Revise cuidadosamente los patrones de handshake personalizados."
