It adds the dimension of transformation over time, so although it may start life as a physical object, such as a computer component, a prosthetic limb or any other physical thing, adding in a fourth dimension, such as an environmental condition, it can change its form and purpose autonomously. The difference between 3D and 4D printing is in the material in the method. In some applications, using a specific material, such as shape memory alloy can be used, with temperature changing the shape of the item. These can be printed in exactly the same way as 3D printed goods,...

Hundreds of HP inkjet printer models vulnerable to critical remote code execution flaws

Almost immediately after announcing a “first of its kind” bug bounty program for printers, offering up to $10,000 per HP printer bug, HP released firmware update patches for hundreds of inkjet printers. “Two security vulnerabilities have been identified with certain HP Inkjet printers,” reads the HP ink printers remote code execution security bulletin. “A maliciously crafted file sent to an affected device can cause a stack or static buffer overflow, which could allow remote code execution.” Read more about the two critical security vulnerabilities affecting hundreds of HP Inkjet printer models on Printer List...
