CVE-2014-6431

Estado: ModificadaMedia (5)—

Desbordamiento de buffer en la función SnifferDecompress en wiretap/ngsniffer.c en el analizador de ficheros DOS Sniffer en Wireshark 1.10.x anterior a 1.10.10 y 1.12.x anterior a 1.12.1 no previene la sobreescritura de datos durante operaciones de copia, lo que permite a atacantes remotos causar una denegación de servicio (caída de la aplicación) a través de un fichero manipulado que provoca escrituras de bytes descomprimidos más allá del final del buffer de salida.
