The MPLS Echo dissector could go into an infinite loop. Discovered by Laurent Butti.
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 1.8.6 or later.
