The AFP dissector could go into a large loop. Reported by Stefan Cornelius.


It may be possible to make Wireshark consume excessive CPU resources by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.


Upgrade to Wireshark 1.8.2, 1.6.10, 1.4.15 or later.
