![]() This vulnerability was the result of an authorization bypass bug which allowed authenticated remote users to install print drivers using the RPC call RpcAddPrinterDriver and specify a driver file located in a remote location. ![]() Balancing security, convenience and backwards compatibility with older devices is challenging. This is like some other subsystems in Windows, but printing is a particularly challenging scenario because both we and customers want the process to be as frictionless as possible. The security model for print drivers relies on a shared responsibility approach where the Windows printing stack and third-party drivers must each play a role in providing functionality and enforcing security promises while avoiding introducing vulnerabilities. What we found is that Windows Protected Print Mode mitigated over half of those vulnerabilities.Īlthough we know some may find changing configurations inconvenient, we believe it is best for overall user security. To put these changes in some context, MORSE did an analysis of past MSRC cases for Windows Print to assess if these changes would help. WPP blocks all third-party drivers and implements a wide range of new security protections. Securing the print stack is challenging, in large part due to the use of third-party drivers. Print bugs played a role in Stuxnet and Print Nightmare, and account for 9% of all Windows cases reported to MSRC. The Spooler runs with high privileges and must load code from the network which is difficult to accomplish with low friction and high security. The Windows print system has been a key target for attackers. One of the largest motivations behind the change is security. This article will explain the case for adopting driverless printing, provide some insights on compatibility, and preview the security improvements provided by Windows Protected Print Mode. Moving away from drivers has allowed us to significantly improve the print stack. Recently, we announced our plan to end servicing for third-party drivers in Windows. We believe users should be Secure-by-Default which is why WPP will eventually be on by default in Windows. We are calling this new platform Windows Protected Print Mode (WPP). The goal was to build a more modern and secure print system that maximizes compatibility and puts users first. This new design represents one of the largest changes to the Windows Print stack in more than 20 years. (for example, a link back to their website).Over the past year, the MORSE team has been working in collaboration with the Windows Print team to modernize the Windows Print System. The license to see if the designer is requesting attribution This icon can be used for both Personal &Ĭommercial purposes and projects, but please check ![]() Converting it to an ICO, JPEG or WebP image format or file type should also be pretty simple (we hope to add that feature to Iconduck soon). If you need this icon available in another format, it should be pretty straight forward to download it as an SVG image file, and then import it into apps like Adobe Photoshop, Crello, Easil or Pablo. It's part of the icon set " File Icons", which has 914 icons in it. It's available to be downloaded in SVG and PNG formats (available in 256, 512, 10 PNG sizes). This open source icon is named "Microsoft Word" and is licensed under the open source ISC license.
