for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause an ESA to
fail to detect and act upon a specific type of file that is attached to an email message.

The vulnerability is due to improper application of message filtering rules to email attachments that contain
a specific type of file and are submitted to an affected appliance. An attacker could exploit this vulnerability
by sending an email message with a crafted attachment to an affected appliance. A successful exploit could allow
the attacker to cause the ESA to fail to detect and act upon possible malware in the email attachment.");
