The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2013:0512 :
Updated httpd packages that fix two security issues, several bugs, and
add various enhancements are now available for Red Hat Enterprise
The Red Hat Security Response Team has rated this update as having low
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.
The httpd packages contain the Apache HTTP Server (httpd), which is
the namesake project of The Apache Software Foundation.
An input sanitization flaw was found in the mod_negotiation Apache
HTTP Server module. A remote attacker able to upload or create files
with arbitrary names in a directory that has the MultiViews options
enabled, could use this flaw to conduct cross-site scripting attacks
against users visiting the site. (CVE-2008-0455, CVE-2012-2687)
It was discovered that mod_proxy_ajp, when used in configurations with
mod_proxy in load balancer mode, would mark a back-end server as
failed when request processing timed out, even when a previous AJP
(Apache JServ Protocol) CPing request was responded to by the
back-end. A remote attacker able to make a back-end use an excessive
amount of time to process a request could cause mod_proxy to not send
requests to back-end AJP servers for the retry timeout period or until
all back-end servers were marked as failed. (CVE-2012-4557)
These updated httpd packages include numerous bug fixes and
enhancements. Space precludes documenting all of these changes in this
advisory. Users are directed to the Red Hat Enterprise Linux 6.4
Technical Notes, linked to in the References, for information on the
most significant of these changes.
All users of httpd are advised to upgrade to these updated packages,
which contain backported patches to correct these issues and add these
enhancements. After installing the updated packages, the httpd daemon
will be restarted automatically.
