Wireshark (formerly known as Ethereal) is a set of network packet analysis software from the Wireshark team. The function of the software is to intercept network packets and display detailed data for analysis. Wireshark suffers from a denial-of-service vulnerability that originates from an infinite loop in the BT SDP parser, which can be exploited by an attacker to cause a denial of service via packet injection or a carefully crafted capture file.
