漏洞描述
中文描述:
Cisco IOS XR Software是美国思科(Cisco)公司的IOS软件系列(包括IOS T、IOS S和IOS XR)中的一套完全模块化、分布式的网络操作系统。 Cisco IOS XR Software 6.3.1版本、6.2.3及之前版本中的UDP广播发送功能存在资源管理错误漏洞,该漏洞源于程序没有正确的处理发送到IPv4兼容助手服务地址的UDP广播数据包。攻击者可通过发送多个UDP广播数据包利用该漏洞造成拒绝服务。
英文描述:
A vulnerability in the UDP broadcast forwarding function of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on the affected device. The vulnerability is due to improper handling of UDP broadcast packets that are forwarded to an IPv4 helper address. An attacker could exploit this vulnerability by sending multiple UDP broadcast packets to the affected device. An exploit could allow the attacker to cause a buffer leak on the affected device, eventually resulting in a DoS condition requiring manual intervention to recover. This vulnerability affects all Cisco IOS XR platforms running 6.3.1, 6.2.3, or earlier releases of Cisco IOS XR Software when at least one IPv4 helper address is configured on an interface of the device. Cisco Bug IDs: CSCvi35625.
