    {
      "lang": "en",
      "value": "During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes. *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected, but products built on top of it might. This vulnerability affects Firefox < 78."

      "value": "Durante la generaci\u00f3n de claves RSA, las implementaciones de bignum usaron una variaci\u00f3n del Binary Extended Euclidean Algorithm que implicaba un flujo significativamente dependiente de la entrada. Esto permiti\u00f3 a un atacante poder llevar a cabo ataques de canal lateral basados ??en electromagnetismo para registrar trazas conllevando a la recuperaci\u00f3n de los principales secretos. *Nota:* Un navegador Firefox no modificado no genera claves RSA en funcionamiento normal y no est\u00e1 afectado, pero los productos creados sobre \u00e9l s\u00ed pueden. Esta vulnerabilidad afecta a Firefox versiones anteriores a 78"
