Docker applies a default seccomp profile that blocks around 40 to 50 syscalls. This meaningfully reduces the attack surface. But the key limitation is that seccomp is a filter on the same kernel. The syscalls you allow still enter the host kernel’s code paths. If there is a vulnerability in the write implementation, or in the network stack, or in any allowed syscall path, seccomp does not help.
Instead of hardcoding the expected string, it captures the actual native code string from the original function before hooking it, then returns that exact string. This way, no matter what browser, no matter what platform, the spoofed toString returns precisely the same string that the original function would have returned. It is, in effect, a perfect forgery.

Fujifilm also sells the newer Instax Square SQ40. It’s similar to the Instax Square SQ1 but with a vintage look that’s more visually striking, yet it’s also more expensive at $199.95. Given it produces similarly good-quality photos, I’d recommend the Instax Square SQ1 or the more capable Instax Mini Evo for $50 more.
