  3. CVE-2024-13176
Issue summary: A timing side-channel which could potentially allow recovering the private key exists in the ECDSA signature computation. Impact summary: A timing side-channel in ECDSA signature computations could allow recovering the private key by an attacker. However, measuring the timing would require either local access to the signing application or a very fast network connection with low latency. There is a timing signal of around 300 nanoseconds when the top word of the inverted ECDSA nonce value is zero. This can happen with significant probability only for some of the supported elliptic curves. In particular the NIST P-521 curve is affected. To be able to measure this leak, the attacker process must either be located in the same physical computer or must have a very fast network connection with low latency. For that reason the severity of this vulnerability is Low. The FIPS modules in 3.4, 3.3, 3.2, 3.1 and 3.0 are affected by this issue.

Summary
  • (es) Resumen del problema: Existe un canal lateral de temporización que potencialmente podría permitir recuperar la clave privada en el cálculo de la firma ECDSA. Resumen del impacto: Un canal lateral de temporización en los cálculos de firmas ECDSA podría permitir que un atacante recupere la clave privada. Sin embargo, para medir el tiempo se necesitaría acceso local a la aplicación de firma o una conexión de red muy rápida con baja latencia. Hay una señal de tiempo de alrededor de 300 nanosegundos cuando la palabra superior del valor nonce ECDSA invertido es cero. Esto puede suceder con una probabilidad significativa sólo para algunas de las curvas elípticas admitidas. En particular, la curva NIST P-521 se ve afectada. Para poder medir esta fuga, el proceso atacante debe estar ubicado en la misma computadora física o debe tener una conexión de red muy rápida con baja latencia. Por esa razón la severidad de esta vulnerabilidad es Baja.
