漏洞描述
中文描述:
Cisco IOS XE Software是美国思科(Cisco)公司的一个操作系统。用于企业有线和无线访问,汇聚,核心和WAN的单一操作系统,Cisco IOS XE降低了业务和网络的复杂性。 Cisco IOS XE Software 存在安全漏洞,该漏洞源于对大碎片隧道协议数据包的处理不当。
英文描述:
A vulnerability in the fragmentation handling code of tunnel protocol packets in Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected system to reload, resulting in a denial of service (DoS) condition. This vulnerability is due to the improper handling of large fragmented tunnel protocol packets. One example of a tunnel protocol is Generic Routing Encapsulation (GRE). An attacker could exploit this vulnerability by sending crafted fragmented packets to an affected system. A successful exploit could allow the attacker to cause the affected system to reload, resulting in a DoS condition. Note: Only traffic directed to the affected system can be used to exploit this vulnerability.
