The remote Amazon Linux AMI host is missing a security update.
A memory corruption flaw was found in the way the openssl_x509_parse()
function of the PHP openssl extension parsed X.509 certificates. A
remote attacker could use this flaw to provide a malicious self-signed
certificate or a certificate signed by a trusted authority to a PHP
application using the aforementioned function, causing the application
to crash or, possibly, allow the attacker to execute arbitrary code
with the privileges of the user running the PHP interpreter.
