CVE-2016-2377

Estado: ModificadaAlta (8.1)—

Existe una vulnerabilidad de desbordamiento de búfer en el manejo del protocolo MXIT en Pidgin. Datos MXIT especialmente manipulados enviados por el servidor podrían resultar potencialmente en una escritura fuera de límites de un byte. Un servidor malicioso puede enviar un contenido negativo de longitud en respuesta a una petición HTTP desencadenando la vulnerabilidad.
