High severity, CVSS 7.5. EPSS: 2.7% chance of exploitation in the next 30 days.

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.
