Estado: ModificadaAlta (7.1)—

A vulnerability in the email message filtering feature of Cisco AsyncOS Software for the Cisco Email Security Appliance could allow an unauthenticated, remote attacker to cause an affected device to run out of memory and stop scanning and forwarding email messages. When system memory is depleted, it can cause the filtering process to crash, resulting in a denial of service (DoS) condition on the device.
