While cool, technically… From a security perspective today I learned that TrueType fonts have arbitrary code execution as a ‘feature’ which seems mostly horrific.

If you think that's bad, until very recently, Windows used to parse ttf directly in the kernel, meaning that a target could look at a webpage, or read an email, and be executing arbitrary code in ring0.

Last I checked there were about 4-10 TTF bugs discovered and actively exploited per year. I think I heard those stats in 2018 or so. This has been a well known and very commonly exploited attack vector for at least 20 years.
