Title:	Cisco Nexus Operating System Address Resolution Protocol Denial of Service Vulnerability (Cisco-SA-20150814-CVE-2015-4323)
Summary:	A vulnerability in the Address Resolution Protocol (ARP) input; packet processing of the Cisco Nexus Operating System (NX-OS) devices could allow an; unauthenticated, adjacent attacker to cause a denial of service (DoS) condition.
Description:	Summary: A vulnerability in the Address Resolution Protocol (ARP) input packet processing of the Cisco Nexus Operating System (NX-OS) devices could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. Vulnerability Insight: The vulnerability is due to improper validation of the ARP packet and the maximum transmission unit (MTU) size, which results in a buffer overflow and could cause a DoS condition. An attacker could exploit the vulnerability by sending a crafted ARP packet to the device. Vulnerability Impact: An exploit could allow the attacker to cause the device to become unavailable due to the DoS condition of the ARP module. Solution: See the referenced vendor advisory for a solution. CVSS Score: 6.1 CVSS Vector: AV:A/AC:L/Au:N/C:N/I:N/A:C
