The Avaya Argent Office reboots in response to certain malformed DNS packets, resulting in a denial of service condition.
The Avaya Argent Office reboots when a packet with an empty payload is sent to UDP port 53 (DNS) on its internal interface. By sending repeated packets to this interface, it is possible to cause the device to reboot continuously, resulting in a denial of service condition.
This vulnerability allows attackers on the same shared network segment to reboot affected devices, thus creating a denial of service condition.
The CERT/CC is currently unaware of a practical solution to this problem.
This vulnerability was reported to the Bugtraq mailing list on 08/07/2001 by Jacek Lipkowski.
