The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2016:1613 :
An update for php is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
PHP is an HTML-embedded scripting language commonly used with the
Apache HTTP Server.
Security Fix(es) :
* It was discovered that PHP did not properly protect against the
HTTP_PROXY variable name clash. A remote attacker could possibly use
this flaw to redirect HTTP requests performed by a PHP script to an
attacker-controlled proxy via a malicious HTTP request.
Red Hat would like to thank Scott Geary (VendHQ) for reporting this
Bug Fix(es) :
* Previously, an incorrect logic in the SAPI header callback routine
caused that the callback counter was not incremented. Consequently,
when a script included a header callback, it could terminate
unexpectedly with a segmentation fault. With this update, the callback
counter is properly managed, and scripts with a header callback
implementation work as expected. (BZ#1346758)
