CVE-2016-2378

Estado: ModificadaAlta (8.1)—

Existe una vulnerabilidad de desbordamiento de búfer en el manejo del protocolo MXIT en Pidgin. Datos especialmente manipulados enviados a través del servidor podrían resultar potencialmente en un desbordamiento de búfer, potencialmente resultando en corrupción de memoria. Un servidor malicioso o un usuario malicioso no filtrado pueden enviar valores de longitud negativa para desencadenar esta vulnerabilidad.
