My takeaway from this “Font rendering on GPUs” deck is that I’m going to let someone else figure it out because literally anything is an easier problem http://terathon.com/font_rendering_sota_lengyel.pdf …

Replying to @havocp
Any time I asked about font or image rendering on GPUs and security, all I got were shrugged shoulders. So even if it is possible, when it is possible, it’ll still be far from mature.

Can you elaborate as to what the security issues you see are? I believe any security issue in GPU font rendering, assuming the renderer is in a memory-safe language, would be reducible to a security issue in WebGL. So it should be no worse than WebGL.

Pretty much all the same ones you’d run into on a CPU minus the tooling to notice it. And yes, it’s the same level of security as WebGL.

WebGL has done a surprisingly good job of being more secure than the naysayers had anticipated. GPU driver exploits are rare. This makes sense, as GLSL is a lot safer than C.
