Subject:      mtr-0.42 is out.
To: BUGTRAQ@SECURITYFOCUS.COM

Hi everyone,

In response to Viktor's recent publication that mtr might be
vulnerable to an attack because it didn't fully drop root privileges,
mtr-0.42 is now out.

As usual, most of the patch is due to the fact that I upgraded
auto-something.

I'm pretty confident that an attack WAS possible. (Although I don't
know of ANY exploit in curses, gtk or mtr, I'm confident there is one).

The offending seteuid call has been in the source since version 0.20.
I seem to remember that the setuid that we use now caused problems
(i.e. not working or not compiling) on some platforms, however, I have
no record of any version having setuid, so I must be imagining things.
The setuid there is obviously correct, and what was intended in the
first place.

Plug: mtr is a full-screen combination of ping and traceroute, and
works much faster than traceroute.


				Roger.
