The vulnerability of the VPN protocol library using “IPsec” in libreswan, related to the swapping of the zero pointer, allows a attacker to perform a type of attack known as “denial-of-service attack”.

The vulnerability of the VPN protocol using “IPsec” with libreswan is related to insufficient validation of user-input data during the processing of IKEv1 ISAKMP SA packets. Exploiting this vulnerability allows a remote attacker to perform a type of attack known as a “denial-of-service” attack...

An issue was discovered in Libreswan 3.x and 4.x before 4.12. When an IKEv1 ISAKMP SA Informational Exchange packet contains a Delete/Notify payload followed by further Notifies that act on the ISAKMP SA such as a duplicated Delete/Notify message a NULL pointer dereference on the deleted state causes the pluto daemon to crash and restart.

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.
