Red Hat Security Advisory 2016-1624-01 - This release of Red Hat JBoss Web Server 3.0.3 Service Pack 1 serves as a update for Red Hat JBoss Web Server 3.0.3 httpd and tomcat. Security Fix: 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.

2. Description:

This release of Red Hat JBoss Web Server 3.0.3 Service Pack 1 serves as a
update for Red Hat JBoss Web Server 3.0.3 httpd and tomcat.

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)

* It was discovered that tomcat 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-2016-5388)

Note: After this update, httpd will no longer pass the value of the Proxy
request header to scripts via the HTTP_PROXY environment variable.

Red Hat would like to thank Scott Geary (VendHQ) for reporting this issue.
