漏洞描述
中文描述:

Cisco Adaptive Security Appliances（ASA，自适应安全设备）Software和Cisco Firepower Threat Defense（FTD）Software都是由美国思科（Cisco）公司开发的程序。前者是一套运行于防火墙中的操作系统。后者是一套提供下一代防火墙服务的统一软件。 Cisco ASA Software和Cisco FTD Software中的Traffic Flow Confidentiality (TFC) over IPsec功能的实现存在安全漏洞。远程攻击者可利用该漏洞造成拒绝服务（设备崩溃）。以下产品和版本受到影响：Cisco Adaptive Security Appliance (ASA) Software 9.6.4版本，9.8.2版本，9.9.1版本；Firepower Threat Defense (FTD) Software 6.2.2版本。

英文描述:

A vulnerability in the implementation of Traffic Flow Confidentiality (TFC) over IPsec functionality in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to an error that may occur if the affected software renegotiates the encryption key for an IPsec tunnel when certain TFC traffic is in flight. An attacker could exploit this vulnerability by sending a malicious stream of TFC traffic through an established IPsec tunnel on an affected device. A successful exploit could allow the attacker to cause a daemon process on the affected device to crash, which could cause the device to crash and result in a DoS condition.
