Summary

The vulnerability in the Cisco Discovery Protocol within Cisco ATA 190 Series Analog Telephone Adapter firmware allows unauthenticated, adjacent attackers to exploit memory management flaws. This flaw is caused by insufficient length validation when processing Cisco Discovery Protocol messages.
