      "value": "A side-channel vulnerability exists in the implementation of BIP-39 mnemonic processing, as observed in Trezor One v1.13.0 to v1.14.0, Trezor T v1.13.0 to v1.14.0, and Trezor Safe v1.13.0 to v1.14.0 hardware wallets. This originates from the BIP-39 standard guidelines, which induce non-constant time execution and specific branch patterns for word searching. An attacker with physical access during the initial setup phase can collect a single side-channel trace. By utilizing profiling-based Deep Learning Side-Channel Analysis (DL-SCA), the attacker can recover the mnemonic code and subsequently steal the assets. The issue was patched."

      "value": "Una vulnerabilidad de canal lateral existe en la implementación del procesamiento mnemotécnico BIP-39, como se observó en las carteras de hardware Trezor One v1.13.0 a v1.14.0, Trezor T v1.13.0 a v1.14.0, y Trezor Safe v1.13.0 a v1.14.0. Esto se origina en las directrices del estándar BIP-39, que inducen una ejecución en tiempo no constante y patrones de ramificación específicos para la búsqueda de palabras. Un atacante con acceso físico durante la fase de configuración inicial puede recolectar un único rastro de canal lateral. Al utilizar el Análisis de Canal Lateral basado en Perfiles y Aprendizaje Profundo (DL-SCA), el atacante puede recuperar el código mnemotécnico y posteriormente robar los activos. El problema fue parcheado."
