CVE-2016-2365

Estado: ModificadaMedia (5.9)—

Existe una vulnerabilidad de denegación de servicio en el manejo del protocolo MXIT en Pidgin. Datos MXIT especialmente manipulados enviados a través del servidor podrían resultar potencialmente en una referencia a puntero nulo. Un servidor malicioso o un atacante que intercepte el tráfico de red puede enviar datos no válidos para desencadenar esta vulnerabilidad y provocar un bloqueo.
