中文描述:

Cisco Adaptive Security Appliance (ASA) 5500-X Series with FirePOWER Services等都是美国思科（Cisco）公司的产品。Cisco Adaptive Security Appliance (ASA) 5500-X Series with FirePOWER Services是一系列防火墙设备；Advanced Malware Protection (AMP) for Networks，7000 Series Appliances是一系列恶意软件防护解决方案。Cisco Firepower System Software是使用在其中的一套防火墙软件。 多款Cisco产品中的Firepower System Software的Pragmatic General Multicast (PGM)协议包的检测引擎解析中存在安全漏洞，该漏洞源于程序没有正确验证输入字段。远程攻击者可通过像检测引擎发送特制的PGM数据包利用该漏洞造成拒绝服务。以下Cisco产品受到影响：Adaptive Security Appliance (ASA) 5500-X Series 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 Security Appliances；FirePOWER 7000 Series Appliances；FirePOWER 8000 Series Appliances；Firepower 9300 Series Security Appliances；FirePOWER Threat Defense for Integrated Services Routers (ISRs)；Industrial Security Appliance 3000；Sourcefire 3D System Appliances；Virtual Next-Generation Intrusion Prevention System (NGIPSv) for VMware。

英文描述:

A vulnerability in the detection engine parsing of Pragmatic General Multicast (PGM) protocol packets for Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition due to the Snort process unexpectedly restarting. The vulnerability is due to improper input validation of the fields in the PGM protocol packet. An attacker could exploit this vulnerability by sending a crafted PGM packet to the detection engine on the targeted device. An exploit could allow the attacker to cause a DoS condition if the Snort process restarts and traffic inspection is bypassed or traffic is dropped. This vulnerability affects Cisco Firepower System Software that has one or more file action policies configured and is running on any of the following Cisco products: Adaptive Security Appliance (ASA) 5500-X Series 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 Security Appliances; FirePOWER 7000 Series Appliances; FirePOWER 8000 Series Appliances; Firepower 9300 Series Security Appliances; FirePOWER Threat Defense for Integrated Services Routers (ISRs); Industrial Security Appliance 3000; Sourcefire 3D System Appliances; Virtual Next-Generation Intrusion Prevention System (NGIPSv) for VMware. Fixed versions: 5.4.0.10 5.4.1.9 6.0.1.3 6.1.0 6.2.0. Cisco Bug IDs: CSCuz00876.
