CVE-2016-5387: Apache HTTPD: Proxy header sets environment

CVE ID

CVE-2016-5387

DESCRIPTION

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.

Unitrends risk assessment:  High

For CentOS6, resolved in httpd-2.2.15-54.el6 included in the latest security update
For CentOS5, resolved in httpd-2.2.3-92.el5_11, not included. Migrate to CentOS6.
