漏洞描述
中文描述:
Cisco Packet Data Network Gateway是美国思科（Cisco）公司的 4G 移动核心网络的关键网络功能。PGW 充当 LTE 网络与其他分组数据网络之间的接口。 Cisco Packet Data Network Gateway 存在安全漏洞，该漏洞源于 Vector Packet Processor 未正确处理格式错误的数据包。
英文描述:
A vulnerability in the Vector Packet Processor (VPP) of Cisco Packet Data Network Gateway (PGW) could allow an unauthenticated, remote attacker to stop ICMP traffic from being processed over an IPsec connection. This vulnerability is due to the VPP improperly handling a malformed packet. An attacker could exploit this vulnerability by sending a malformed Encapsulating Security Payload (ESP) packet over an IPsec connection. A successful exploit could allow the attacker to stop ICMP traffic over an IPsec connection and cause a denial of service (DoS).
