The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2016:1422 :
An update for httpd is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security
impact of Important. 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.
The httpd packages provide the Apache HTTP Server, a powerful,
efficient, and extensible web server.
Security Fix(es) :
* It was discovered that httpd used the value of the Proxy header from
HTTP requests to initialize the HTTP_PROXY environment variable for
CGI scripts, which in turn was incorrectly used by certain HTTP client
implementations to configure the proxy for outgoing HTTP requests. A
remote attacker could possibly use this flaw to redirect HTTP requests
performed by a CGI script to an attacker-controlled proxy via a
malicious HTTP request. (CVE-2016-5387)
Note: After this update, httpd will no longer pass the value of the
Proxy request header to scripts via the HTTP_PROXY environment
Red Hat would like to thank Scott Geary (VendHQ) for reporting this
Bug Fix(es) :
* In a caching proxy configuration, the mod_cache module would treat
content as stale if the Expires header changed when refreshing a
cached response. As a consequence, an origin server returning content
without a fixed Expires header would not be treated as cacheable. The
mod_cache module has been fixed to ignore changes in the Expires
header when refreshing content. As a result, such content is now
cacheable, improving performance and reducing load at the origin
* The HTTP status code 451 'Unavailable For Legal Reasons' was not
usable in the httpd configuration. As a consequence, modules such as
mod_rewrite could not be configured to return a 451 error if required
for legal purposes. The 451 status code has been added to the list of
available error codes, and modules can now be configured to return a
451 error if required. (BZ#1353269)
