I'm not sure how exploitable this is without control over a disk in the first place. So, I'll call it B1 for now, but I think we need to discuss this.

@ maintainer(s): Could you please bump to v1.0.6.1 first (https://sourceforge.net/p/gptfdisk/code/ci/f063fe08e424c99f133df18bf9dce49c851bcb0a/) before stabilize?
