漏洞描述
中文描述:
Cisco Email Security Appliance（ESA）是美国思科（Cisco）公司的一个电子邮件安全设备。 Cisco Email Security Appliance DNS Verification 存在安全漏洞，该漏洞源于受影响软件对 DNS 名称解析的错误处理不足。攻击者可以通过发送由受影响设备处理的特殊格式的电子邮件来利用此漏洞。成功的利用可能导致设备无法从管理界面访问或在一段时间内处理其他电子邮件消息，直到设备恢复，从而导致 DoS 条件。
英文描述:
A vulnerability in the DNS-based Authentication of Named Entities (DANE) email verification component of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient error handling in DNS name resolution by the affected software. An attacker could exploit this vulnerability by sending specially formatted email messages that are processed by an affected device. A successful exploit could allow the attacker to cause the device to become unreachable from management interfaces or to process additional email messages for a period of time until the device recovers, resulting in a DoS condition. Continued attacks could cause the device to become completely unavailable, resulting in a persistent DoS condition.
