中文标题:
Cisco StarOS 缓冲区错误漏洞
英文标题:
Cisco StarOS IPv6 Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco StarOS是美国思科（Cisco）公司的一套虚拟化操作系统。 Cisco StarOS 21.18.3之前版本中的IPv6实现存在缓冲区错误漏洞，该漏洞源于程序没有充分验证所接收的IPv6流量。远程攻击者可通过发送特制的IPv6数据包利用该漏洞造成拒绝服务。以下产品及版本受到影响：Cisco ASR 5000 Series Aggregation Services Routers；Cisco Virtualized Packet Core-Single Instance (VPC-SI)。
英文描述:
A vulnerability in the IPv6 implementation of Cisco StarOS could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient validation of incoming IPv6 traffic. An attacker could exploit this vulnerability by sending a crafted IPv6 packet to an affected device with the goal of reaching the vulnerable section of the input buffer. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. This vulnerability is specific to IPv6 traffic. IPv4 traffic is not affected.
