Summary		(es) Se ha identificado una vulnerabilidad en OpenV2G (todas las versiones anteriores a la V0.9.6). La función de análisis de EXI de OpenV2G no tiene una comprobación de longitud al analizar números de serie X509. Por lo tanto, un atacante podría introducir un desbordamiento de búfer que provoque una corrupción de la memoria.
