In Wireshark 2.2.0 to 2.2.6, the ROS dissector could crash with a NULL pointer dereference. This was addressed in epan/dissectors/asn1/ros/packet-ros-template.c by validating an OID.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
