Cisco Catalyst 4000系列交换机TCP拒绝服务漏洞
漏洞描述信息
Cisco IOS软件中Cisco Catalyst 4000系列交换机的-ingress数据包处理功能存在一个漏洞，未经身份验证的远程攻击者可能利用该漏洞导致受影响设备发生拒绝服务(DoS)状况。该漏洞是由于在特定Cisco Catalyst 4000系列交换机上处理定向到设备的TCP数据包时资源分配不当造成的。攻击者可能通过向受影响设备发送精心构造的TCP流来利用此漏洞。成功的利用可能导致受影响设备耗尽缓冲区资源，从而破坏控制平面和管理平面协议的运行，导致DoS状况。此漏洞只能被定向到受影响设备的流量触发，而不能通过流经受影响设备的流量进行利用。

Cisco Catalyst 4000 Series Switches TCP Denial of Service Vulnerability
漏洞描述信息
A vulnerability in the ingress packet processing function of Cisco IOS Software for Cisco Catalyst 4000 Series Switches could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper resource allocation when processing TCP packets directed to the device on specific Cisco Catalyst 4000 Series Switches. An attacker could exploit this vulnerability by sending crafted TCP streams to an affected device. A successful exploit could cause the affected device to run out of buffer resources, impairing operations of control plane and management plane protocols, resulting in a DoS condition. This vulnerability can be triggered only by traffic that is destined to an affected device and cannot be exploited using traffic that transits an affected device.
