Printers are no exception. While there are numerous potential attack vectors, two standard ways of importing foreign code are present in most of today's printers and MFPs by design: the ability to perform firmware updates and to install additional software packages. Furthermote, a short introduction to the danger of buffer overflows in embedded devices is given.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
