Summary
In Libreswan 3.27 an assertion failure can lead to a pluto IKE daemon restart. An attacker can trigger a NULL pointer dereference by initiating an IKEv2 IKE_SA_INIT exchange, followed by a bogus INFORMATIONAL exchange instead of the normallly expected IKE_AUTH exchange. This affects send_v2N_spi_response_from_state() in programs/pluto/ikev2_send.c that will then trigger a NULL pointer dereference leading to a restart of libreswan.

Un atacante puede iniciar una desreferencia de puntero NULL enviando dos paquetes IKEv2 (init_IKE y delete_IKE) en modo 3des_cbc a un servidor Libreswan. Esto afecta a send_v2N_spi_response_from_state en pprograms/pluto/ikev2_send.c cuando se crea con Network Security Services (NSS)."
