      "value": "OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. This leads to memory corruption and local code execution because of an error in the XMSS key parsing algorithm. NOTE: the XMSS implementation is considered experimental in all released OpenSSH versions, and there is no supported way to enable it when building portable OpenSSH."

      "value": "OpenSSH 7.7 a 7.9 y 8.x anterior de la versi\u00f3n  8.1, cuando se compila con un tipo de clave experimental, tiene un desbordamiento de entero de identificaci\u00f3n  previa si un cliente o servidor est\u00e1 configurado para usar una clave XMSS especialmente dise\u00f1ada. Esto conduce a la corrupci\u00f3n de la memoria y la ejecuci\u00f3n del c\u00f3digo local debido a un error en el algoritmo de an\u00e1lisis de claves XMSS. NOTA: la implementaci\u00f3n de XMSS se considera experimental en todas las versiones de OpenSSH lanzadas, y no hay una forma compatible para habilitarla al crear OpenSSH port\u00e1til."
