Security Fix(es):
-
libreswan: Invalid IKEv2 REKEY proposal causes restart (CVE-2023-38710)
-
libreswan: Invalid IKEv1 Quick Mode ID causes restart (CVE-2023-38711)
-

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.
