software

With everything legal and in line with the ethical questions in software development, is it allowed to use an open source product in my software that I charge a fee for when selling?

Scenario: I've developed an PHP Content Management System (CMS) and use some Linux executables licensed under GPL or LGPL in my CMS to accomplish various tasks like image editing. I'm selling the CMS and also including the executables when I deliver the product.

I do not edit the source code of the GPL software, just using it.
