Wireshark Denial of Service Vulnerability

Multiple vulnerabilities have been identified in Wireshark, which can be exploited by malicious people to cause a DoS (Denial of Service).

1. A NULL pointer dereference error in the ANSI A dissector can be exploited to cause a crash via a specially crafted packet.
2. An error in the IEEE 802.11 dissector can be exploited to cause an infinite loop via a specially crafted packet.
3. An error in the MP2T dissector when allocating memory can be exploited to cause a crash via a specially crafted packet.
   NOTE: A weakness exists in the pcap and pcap-ng file parsers when reading ERF data and can cause a crash via a specially crafted trace file.
