CVE-2016-2373

Estado: ModificadaMedia (5.9)—

Existe una vulnerabilidad de servicio en el manejo del protocolo MXIT en Pidgin. Datos MXIT especialmente manipulados enviados a través del servidor podrían resultar potencialmente en una escritura fuera de límites. Un servidor o usuario malicioso puede enviar un mood inválido para desencadenar esta vulnerabilidad.
