Hey,

I cannot reproduce your exploit.

Using the stock sudoers file only with the modification

%sudo ALL=(ALL) ALL

and the place for running X applications as root is commented out.

## Run X applications through sudo; HOME is used to find the
## .Xauthority file.  Note that other programs use HOME to find
## configuration files and this may lead to privilege escalation!
# Defaults env_keep += "HOME"

cheers,

Heiko
