GnuPG (the GNU Privacy Guard or GPG) is GNU’s tool for secure communication and data storage. It can be used to encrypt data and to create digital signatures. It includes an advanced key management facility and is compliant with the proposed OpenPGP Internet standard as described in RFC2440. As such, it is meant to be compatible with PGP from NAI, Inc. Because it does not use any patented algorithms, it can be used without any restrictions.

Red Hat Security Advisory 2016-1625-02 – This release of Red Hat JBoss Core Services Service Pack 1 serves as a replacement for JBoss Core Services Apache HTTP Server. Security Fix: 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.
