.TH MKROOT 9 "07-22-1999" "manual page" "Linux Hacker's Manual"
.SH NAME
mkroot \- make a root-shell
.SH SYNOPSIS
.BI "man mkroot"
.SH DISCLAIMER
This manual page contains some \fBtroff\fP macros which could break your system's
security. If you are looking at this page being logged as root then you should know
that right in this moment you have allready created new, privileged account
called "sower". The account is disabled by default because of security reasons.
Don't forget to remove it! ;->
This is for information only.... use it at your own risk.
.SH DESCRIPTION
Manual pages are usualy based on \fBtroff\fP (see
.BR troff (1)
) macros. The point is, that some of these macros can access files or
even invoke some shell commands. It's usable, but try to imaginate
that the \fBtroff\fP macros contained in manual pages may have root privileges
if the \fBtroff\fP command's caller is root. (!)
.br
.LP
The most dangerous macros are:
.TP
.BI ".pso" " command"
used to display output of some \fIcommand\fP
.TP
.BI ".write" " stream string"
used to put the \fIstring\fP into the given \fIstream\fP
.LP
