First published: Mon Apr 17 2023(Updated: )

When an IKEv1 Aggressive Mode packet is received with only unacceptable crypto algorithms, the response packet is not sent with a zero responder SPI. When a subsequent packet is received where the sender re-uses the libreswan responder SPI as its own initiator SPI, the pluto daemon state machine crashes. No remote code execution is possible. <a href="https://github.com/libreswan/libreswan/issues/1039">https://github.com/libreswan/libreswan/issues/1039</a>
