Descriptions

crypto/x509/x509_vfy.c in OpenSSL 1.0.x before 1.0.0e does not initialize certain structure members, which makes it easier for remote attackers to bypass CRL validation by using a nextUpdate value corresponding to a time in the past.

crypto/x509/x509_vfy.c en OpenSSL v1.0.x antes de v1.0.0e no inicializa algunos miembros de una estructura, lo que facilita a los atacantes remotos a la hora de evitar la validaciĆ³n de la CRL utilizando un valor nextUpdate que corresponde a un momento en el pasado.
