Cisco IP Phones 7902/7905/7912, ATA 186/188, Unity Express, ACNS, and Subscriber Edge Services Manager (SESM) allows remote attackers to cause a denial of service (crash or instability) via a compressed DNS packet with a label length byte with an incorrect offset.

The remote host is running the Delegate DNS Service.  This version of Delegate is vulnerable to a remote Denial of Service flaw.  An attacker exploiting this flaw would send a malformed DNS query to the host. Successful exploitation would result in the loss of availability.
