Such a tool is often referred to as a network analyzer, network protocol analyzer or sniffer.  Wireshark, formerly known as Ethereal, can be used to examine the details of traffic at a variety of levels ranging from connection-level information to the bits that make up a single packet. Packet capture can provide a network administrator with information about individual packets such as transmit time, source, destination, protocol type and header data. This information can be useful for evaluating security events and troubleshooting network security device issues.\r\n\r\nSecurity Fix(es):\r\n\r\nIn Wireshark 3.2.0 to 3.2.1, 3.0.0 to 3.0.8, and 2.6.0 to 2.6.14, the LTE RRC dissector could leak memory.
