Esto solo afecta a procesadores compatibles con la extensi\u00f3n AVX2, pero no la ADX, como Intel Haswell (cuarta generaci\u00f3n). Nota: El impacto de este problema es similar a CVE-2017-3736, CVE-2017-3732 y CVE-2015-3193. Se han visto afectadas las versiones 1.0.2-1.0.2m y 1.1.0-1.1.0g de OpenSSL. Se ha solucionado en OpenSSL 1.0.2n. Debido a la baja gravedad de este problema, no se va a lanzar una nueva versi\u00f3n de OpenSSL 1.1.0 en este momento. La correcci\u00f3n se aplicar\u00e1 en OpenSSL 1.1.0h cuando est\u00e9 disponible. La correcci\u00f3n tambi\u00e9n estar\u00e1 disponible en el commit con ID e502cc86d en el repositorio Git de OpenSSL."}], "id": "CVE-2017-3738", "lastModified": "2022-08-19T11:49:42.737", "metrics":
