Cisco Unified IP Conference Station 7937G Denial of Service Vulnerability
http://tools.cisco.com/security/center/content/CiscoSecurityNotice/CVE-2013-3435
CVE ID: CVE-2013-3435
Release Date: 2013 July 19 16:46 UTC (GMT)

Summary
A vulnerability in processing network traffic of the Cisco Unified IP
Conference Station 7937G could allow an unauthenticated, remote attacker to
create a denial of service (DoS) condition on the affected device.
The vulnerability is due to resource constraints in processing a high rate of
network traffic. An attacker could exploit this vulnerability by sending a
high rate of TCP packets to the device. An exploit could allow the attacker to
render the device unable to communicate on the network until the DoS condition
ends.
