From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The claim of the person you're replying to is that even if the binaries were tampered, Ventoy wouldn't be able to do anything.
Even if the original issue had anything to do with ISOs, he's way overestimating the level of protection on many install ISOs, in my experience—they're just disk images, and presumably all the files read off them are passing through Ventoy itself. Even if you find one that performs some kind of verification, easy enough to change a jump instruction to a no-op somewhere in the machine code guts of a file as it passes through Ventoy, and prevent the verification from executing. (The difficult part is figuring out which instruction to change, but people have done it before.)
No, I'm saying the way ISOs are written, you couldn't just, say, inject changes via text tools or whatever like the xz attack.
I'm not aware of HOW a binary blob not knowing specifically what it was going to attack COULD attack anything in a resting and isolated state like it would be with Ventoy.
