This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
Current Description
OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8 before 0.9.8c, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents OpenSSL from correctly verifying X.509 and other certificates that use PKCS #1.

OpenSSL en versiones anteriores a 0.9.7, 0.9.7 en versiones anteriores a 0.9.7k y 0.9.8 en versiones anteriores a 0.9.8c, cuando usa una clave RSA con exponente 3, elimina relleno PKCS-1 antes de generar un hash, lo que permite a atacantes remotos falsificar una firma PKCS #1 v1.5 que está firmada por dicha clave RSA e impide a OpenSSL verificar correctamente los certificados X.509 y otros que utilizan PKCS #1.
