Descriptions

A vulnerability in the malware detection functionality in Cisco Advanced Malware Protection (AMP) in Cisco AsyncOS Software for Cisco Email Security Appliances (ESAs) could allow an unauthenticated remote attacker to exhaust resources on an affected device. The vulnerability is due to insufficient control over system memory allocation. An attacker could exploit this vulnerability by sending a crafted email through the targeted device. A successful exploit could allow the attacker to cause an email attachment that contains malware to be delivered to a user and cause email processing delays.
