漏洞描述
中文描述:

Cisco ASA Software和FTD Software中的TCP代理功能存在输入验证错误漏洞。该漏洞源于网络系统或产品未对输入的数据进行正确的验证。以下产品及版本受到影响：Cisco 3000 Series Industrial Security Appliances；ASA 1000V Cloud Firewall；ASA 5500 Series Adaptive Security Appliances；ASA 5500-X Series Firewalls；ASA Services Module for Cisco Catalyst 6500 Series Switches和Cisco 7600 Series Routers；Adaptive Security Virtual Appliance；Firepower 2100 Series；Firepower 4100 Series；Firepower 9300 Security Appliances。

英文描述:

A vulnerability in the TCP proxy functionality for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to an error in TCP-based packet inspection, which could cause the TCP packet to have an invalid Layer 2 (L2)-formatted header. An attacker could exploit this vulnerability by sending a crafted TCP packet sequence to the targeted device. A successful exploit could allow the attacker to cause a DoS condition.
