Description Chris Evans 1999-05-13 21:01:07 UTC
Hi

in.ntalkd and in.talkd are launched from inetd.conf with
user field set to "root".

A very simple and obviously correct change can limit the
security damage a hole in either of these daemons will
cause.

In RedHat6.1, please change the "root" field to "talkd.tty".
Group tty is the only special privilege required. "talkd"
should be a new user who owns no files and has a null shell
in /etc/passwd. Don't use the overloaded user "nobody".

This should take someone about, ooh, 10 minutes :-)

Chris

Um, using the overloaded nobody.
