- Summary
- [none]
- Details
-
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 IKESAINIT exchange, followed by a bogus INFORMATIONAL exchange instead of the normallly expected IKEAUTH exchange. This affects sendv2Nspiresponsefromstate() in programs/pluto/ikev2_send.c that will then trigger a NULL pointer dereference leading to a restart of libreswan.
