The remote Red Hat host is missing one or more security updates.
An update for httpd is now available for Red Hat Enterprise Linux 5
and Red Hat Enterprise Linux 6.
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
