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.
Affects 1.4.0 to 1.4.14, 1.6.0 to 1.6.9, 1.8.0 to 1.8.1 and is fixed in upstream 1.8.2, 1.6.10, and 1.4.15 versions.
Note: 1.0.x does not have the RTPS2 dissector, 1.2.x does so is probably affected.
