Cisco Firepower Threat Defense 安全漏洞
英文标题:
Cisco Firepower Threat Defense Software Snort Out of Memory Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Firepower Threat Defense（FTD）是美国思科（Cisco）公司的一套提供下一代防火墙服务的统一软件。 Cisco Firepower Threat Defense (FTD) 存在安全漏洞，该漏洞源于某些 Snort 事件的内存管理不足。攻击者可以通过发送一系列精心设计的 IP 数据包来导致受影响设备出现内存不足的情况，从而导致 DoS。
英文描述:
A vulnerability in the Snort detection engine integration for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause unlimited memory consumption, which could lead to a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient memory management for certain Snort events. An attacker could exploit this vulnerability by sending a series of crafted IP packets that would generate specific Snort events on an affected device. A sustained attack could cause an out of memory condition on the affected device. A successful exploit could allow the attacker to interrupt all traffic flowing through the affected device. In some circumstances, the attacker may be able to cause the device to reload, resulting in a DoS condition.
