The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in epan/dissectors/packet-vlan.c due to limiting VLAN tag nesting to restrict the recursion depth. A remote attacker can trick the victim into opening a specially crafted packet trace file and cause the VLAN dissector to crash.
