Wow, that's super interesting. As you say, it's a contrived CTF example, but I'm pretty shocked that it's possible to read and write arbitrary process memory without importing any packages (especially unsafe, of course).

I'm also surprised that a fix has been theorized at least as far back as 2010[1], but not implemented. Is adding one layer of internal pointer redirection for interfaces, slices, and strings really that much of a performance concern?
