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

Comment 4 Riccardo Schirone 2019-05-16 09:22:36 UTC 
An heap out-of-bound read is possible in assign_addr_port_id() in epan/dissectors/packet-dof.c, when the DOF dissector is used. This could lead to a crash or to a leak of the memory content.
