Re: Major Linux security hole gapes open
That unencrypted /boot partition rears its ugly head again.
Last year you just had to hit backspace exactly 28 times and it would drop you to a shell.
Sometimes I wonder if these backdoors to /boot are intentional.

I might be wrong but I think if you have entire filesystem encrypted, having acces to /boot (even root acces) doesn't give you any way to get to files. Not even root can decrypt without the key/password, which is not hashed anywhere.

Yeah, true FDE has been possible for at least 2 years with grub2, but none of the installers have been updated to make it easy to set up.evening_hunger wrote:I might be wrong but I think if you have entire filesystem encrypted, having acces to /boot (even root acces) doesn't give you any way to get to files.

With OpenBSD, it's literally one bioctl command prior to installation.

Re: Major Linux security hole gapes open
I consider myself relatively dumb, but was able to do this when installing my Debian 2 years ago. So not that tragic after all:)
