中文描述:

Cisco Adaptive Security Appliance (ASA) 5500-X Series Firewalls with FirePOWER Services等都是美国思科（Cisco）公司的安全防火墙设备。Firepower System Software是其中的一套防火墙操作系统。detection engine是其中的一个入侵检测引擎。 多款Cisco产品中的Firepower System Software 6.0.0及之后的版本中detection引擎的安全套接层协议数据包重组功能存在安全漏洞，该漏洞源于程序没有正确的处理SSL连接状态的改变。远程攻击者可利用该漏洞造成拒绝服务（系统内存消耗过多）。以下产品受到影响：Cisco Adaptive Security Appliance (ASA) 5500-X Series Firewalls with FirePOWER Services；Adaptive Security Appliance (ASA) 5500-X Series Next-Generation Firewalls；Advanced Malware Protection (AMP) for Networks；7000 Series Appliances；Advanced Malware Protection (AMP) for Networks；8000 Series Appliances；Firepower 4100 Series Appliances；FirePOWER 7000 Series Appliances；FirePOWER 8000 Series Appliances；Firepower 9300 Series Security Appliances；Firepower Threat Defense for Integrated Services Routers (ISRs)；Firepower Threat Defense Virtual for VMware；Industrial Security Appliance 3000；Sourcefire 3D System Appliances。

英文描述:

A vulnerability in the Secure Sockets Layer (SSL) packet reassembly functionality of the detection engine in Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause the detection engine to consume excessive system memory on an affected device, which could cause a denial of service (DoS) condition. The vulnerability is due to the affected software improperly handling changes to SSL connection states. An attacker could exploit this vulnerability by sending crafted SSL connections through an affected device. A successful exploit could allow the attacker to cause the detection engine to consume excessive system memory on the affected device, which could cause a DoS condition. The device may need to be reloaded manually to recover from this condition. This vulnerability affects Cisco Firepower System Software Releases 6.0.0 and later, running on any of the following Cisco products: Adaptive Security Appliance (ASA) 5500-X Series Firewalls with FirePOWER Services, Adaptive Security Appliance (ASA) 5500-X Series Next-Generation Firewalls, Advanced Malware Protection (AMP) for Networks, 7000 Series Appliances, Advanced Malware Protection (AMP) for Networks, 8000 Series Appliances, Firepower 4100 Series Appliances, FirePOWER 7000 Series Appliances, FirePOWER 8000 Series Appliances, Firepower 9300 Series Security Appliances, Firepower Threat Defense for Integrated Services Routers (ISRs), Firepower Threat Defense Virtual for VMware, Industrial Security Appliance 3000, Sourcefire 3D System Appliances.
