Descriptions

Integer overflow in the dissect_tnef function in epan/dissectors/packet-tnef.c in the TNEF dissector in Wireshark 1.10.x before 1.10.13 and 1.12.x before 1.12.4 allows remote attackers to cause a denial of service (infinite loop) via a crafted length field in a packet.

Desbordamiento de enteros en la función dissect_tnef en epan/dissectors/packet-tnef.c en el disector TNEF en Wireshark 1.10.x anterior a 1.10.13 y 1.12.x anterior a 1.12.4 permite a atacantes remotos causar una denegación de servicio (bucle infinito) a través de un campo de longitud manipulado en un paquete.

Wireshark, previously known as Ethereal, is a network protocol analyzer, which is used to capture and browse the traffic running on a computer network. Several denial of service flaws were found in Wireshark. Wireshark could crash or stop responding if it read a malformed packet off a network, or opened a malicious dump file.
