This fellow makes cool electronics and tinkering videos. Very witty and humorous, and self deprecating.
Ahahaha, seems this one goes for more comedy:
RE: PSA: Lunix haz teh bugz
does this mean:
“A user with sudo privileges can cause sudo to use a device number of the user’s choosing by creating a symbolic link from the sudo binary to a name that contains a space, followed by a number.”
Root can become rooooot
That's not really correct. Sudo is more secure alternative for set-uid scripts, so it allows a non-privileged user to run a limited set of commands as another user where the details depend on the configuration of the
sudoersfile. Ubuntu started allowing a certain group to run all commands as root but this is just one configuration.
To go back to the vulnerability: if the user could execute a certain command but couldn't run as root before, allegedly using this vulnerability may allow them to overwrite the
sudoersfile so that they can run anything they want as root.
