漏洞描述
中文描述:

Cisco Firepower Threat Defense（FTD）和Cisco Adaptive Security Appliances Software（ASA Software）都是美国思科（Cisco）公司的产品。Cisco Firepower Threat Defense是一套提供下一代防火墙服务的统一软件。Cisco Adaptive Security Appliances Software是一套防火墙和网络安全平台。该平台提供了对数据和网络资源的高度安全的访问等功能。 Cisco ASA Software和FTD Software中的IPv6 DNS数据包处理过程存在输入验证错误漏洞，该漏洞源于程序没有正确对IPv6 DNS数据包中的字段进行长度验证。远程攻击者可利用该漏洞造成拒绝服务。

英文描述:

A vulnerability in DNS over IPv6 packet processing for Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the device to unexpectedly reload, resulting in a denial of service (DoS) condition. The vulnerability is due to improper length validation of a field in an IPv6 DNS packet. An attacker could exploit this vulnerability by sending a crafted DNS query over IPv6, which traverses the affected device. An exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. This vulnerability is specific to DNS over IPv6 traffic only.
