CVE-2015-6291 [HIGH] CWE-20 Cisco Email Security Appliance Email Scanner Denial of Service Vulnerability
Cisco Email Security Appliance Email Scanner Denial of Service Vulnerability
A vulnerability in the email message filtering feature of Cisco AsyncOS for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause an ESA device to become unavailable due to a denial of service (DoS) condition.
The vulnerability is due to improper input validation when an email attachment contains corrupted fields and is filtered by the ESA. An attacker could exploit this vulnerability by sending a crafted email with an attachment to the ESA. A successful exploit could allow the attacker to cause a DoS condition. While the attachment is being filtered, memory is consumed at at high rate until the filtering process restarts. When the process restarts, it will resume processi
