The remote Amazon Linux AMI host is missing a security update.
Openswan is a free implementation of Internet Protocol Security
(IPsec) and Internet Key Exchange (IKE). IPsec uses strong
cryptography to provide both authentication and encryption services.
These services allow you to build secure tunnels through untrusted
A use-after-free flaw was found in the way Openswan's pluto IKE daemon
used cryptographic helpers. A remote, authenticated attacker could
send a specially-crafted IKE packet that would crash the pluto daemon.
This issue only affected SMP (symmetric multiprocessing) systems that
have the cryptographic helpers enabled.
