英文标题:
Cisco IOS XR Software IPsec Packet Processor Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco IOS XR是美国思科（Cisco）公司的一套为其网络设备开发的操作系统。 Cisco IOS XR中的IPsec数据包处理器存在资源管理错误漏洞，该漏洞源于该处理器没有正确处理数据包。远程攻击者可通过发送恶意的ICMP错误消息利用该漏洞耗尽IPsec内存，导致拒绝服务。以下产品及版本受到影响：Cisco IOS XR（release）6.4.3之前版本，6.6.3之前版本，7.0.2之前版本，7.1.1之前版本。
英文描述:
A vulnerability in the IPsec packet processor of Cisco IOS XR Software could allow an unauthenticated remote attacker to cause a denial of service (DoS) condition for IPsec sessions to an affected device. The vulnerability is due to improper handling of packets by the IPsec packet processor. An attacker could exploit this vulnerability by sending malicious ICMP error messages to an affected device that get punted to the IPsec packet processor. A successful exploit could allow the attacker to deplete IPsec memory, resulting in all future IPsec packets to an affected device being dropped by the device. Manual intervention is required to recover from this situation.
