CVE-2016-2376

Estado: ModificadaAlta (8.1)—

Existe una vulnerabilidad de desbordamiento de búfer en el manejo del protocolo MXIT en Pidgin. Datos MXIT especialmente manipulados enviados desde el servidor podrían resultar potencialmente en ejecución de código arbitrario. Un servidor malicioso o un atacante que intercepte el tráfico red puede enviar un tamaño inválido para un paquete que desencadenará un desbordamiento de búfer.
