英文标题:
Multiple Cisco Products Snort Memory Leak Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Products Snort是美国思科(Cisco)公司的一个用于思科产品的Snort引擎。 Cisco Products Snort Memory 存在安全漏洞,该漏洞源于 Snort 检测引擎处理 ICMP 数据包时内存资源管理不当造成的。攻击者可以通过受影响的设备发送一系列 ICMP 数据包来利用此漏洞。成功的利用可能允许攻击者耗尽受影响设备上的资源,从而导致设备重新加载。
英文描述:
Multiple Cisco products are affected by a vulnerability in the way the Snort detection engine processes ICMP traffic that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper memory resource management while the Snort detection engine is processing ICMP packets. An attacker could exploit this vulnerability by sending a series of ICMP packets through an affected device. A successful exploit could allow the attacker to exhaust resources on the affected device, causing the device to reload.
