(RHSA-2016:1851) Important: Red Hat JBoss Core Services Apache HTTP 2.4.6 Service Pack 1 security update

This release of Red Hat JBoss Core Services Service Pack 1 serves as a replacement for JBoss Core Services Apache HTTP Server.

Security Fix(es):

• It was discovered that Apache HTTP Server 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, Apache HTTP Server 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.
