First published: Wed Apr 12 2017(Updated: )
In Wireshark 2.2.0 to 2.2.5, the DOF dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-dof.c by using a different integer data type and adjusting a return value.
