CVE-2016-2369

Estado: ModificadaMedia (5.9)—

Existe una vulnerabilidad de referencia a puntero NULL en el manejo del protocolo MXIT en Pidgin. Datos MXIT especialmente manipulados enviados a través del servidor podrían resultar potencialmente en una vulnerabilidad de denegación de servicio. Un servidor malicioso puede enviar un paquete que comienza con un byte NULL desencadenando la vulnerabilidad.
