The remote Amazon Linux AMI host is missing a security update.
A buffer overflow flaw was found in Openswan. If Opportunistic
Encryption were enabled ('oe=yes' in '/etc/ipsec.conf') and an RSA key
configured, an attacker able to cause a system to perform a DNS lookup
for an attacker-controlled domain containing malicious records (such
as by sending an email that triggers a DKIM or SPF DNS record lookup)
could cause Openswan's pluto IKE daemon to crash or, potentially,
execute arbitrary code with root privileges. With 'oe=yes' but no RSA
key configured, the issue can only be triggered by attackers on the
local network who can control the reverse DNS entry of the target
system. Opportunistic Encryption is disabled by default.
