Descriptions
The OpenSSL extension of Ruby (Git trunk) versions after 2011-09-01 up to 2011-11-03 always generated an exponent value of '1' to be used for private RSA key generation. A remote attacker could use this flaw to bypass or corrupt integrity of services, depending on strong private RSA keys generation mechanism.
La extensión OpenSSL de Ruby (Git trunk) versiones posteriores al 01-09-2011 hasta el 03-11-2011, siempre generó un valor de exponente de "1" para ser usado para la generación de claves RSA privadas. Un atacante remoto podría usar este fallo para omitir o dañar la integridad de los servicios, dependiendo de un mecanismo de generación de claves RSA privadas fuerte.
