Discussion

Openswan and strongSwan DPD Packet Remote Denial Of Service Vulnerability

Openswan and strongSwan are prone to a remote denial-of-service vulnerability because they fail to properly handle certain Dead Peer Detection (DPD) packets.

Attackers can exploit this issue to crash the pluto IKE daemon, denying access to legitimate users.

Versions *prior to* the following are affected:

Openswan 2.6.21
Openswan 2.4.14
strongSwan 4.2.14
strongSwan 2.8.9
