Vulnerability Description
An issue was discovered in Libreswan before 4.12. When an IKEv2 Child SA REKEY packet contains an invalid IPsec protocol ID number of 0 or 1, an error notify INVALID_SPI is sent back. The notify payload's protocol ID is copied from the incoming packet, but the code that verifies outgoing packets fails an assertion that the protocol ID must be ESP (2) or AH(3) and causes the pluto daemon to crash and restart. NOTE: the earliest affected version is 3.20.

Libreswan 安全漏洞
Vulnerability Description
Libreswan是一个类似于Openswan的IPsec实现，它主要用于保证数据传输中的安全性、完整性问题。 Libreswan 4.12之前版本存在安全漏洞，该漏洞源于在IKEv2子安全关联（Child SA）的重新协商（REKEY）数据包中，如果包含了无效的IPsec协议ID号（0或1），会发送一个错误通知（INVALID_SPI）。这个通知负载的协议ID是从传入的数据包中复制的，但是验证传出数据包的代码会失败，因为协议ID必须是ESP（2）或AH（3），这导致pluto守护进程崩溃并重新启动。
