Ethereal contains a flaw that may allow a remote denial of service. The issue is triggered due to the 'dissect_attribute_value_pairs' function in packet-radius.c. It is possible for a remote attacker to send a specially crafted RADIUS packet, which triggers a NULL derefence and will result in loss of availability for the application.
