Package: update-inetd
Version: 4.31
Severity: normal
While debugging #531565 I noticed that there was another problem with
the invocation of itox in update-inetd. If the inetd.conf line includes
any shell meta-characters (in my case, it started with a #-comment),
these are not escaped when the command is run. This is what caused
update-inetd to break debconf when run in my postinst, since the
commande "echo $modearg | itox >&2" actually ended up as an 'echo'
command followed by a long comment, meaning that update-inetd ended up
writing a newline to STDOUT.
Proposed fix:

if (-f "/usr/sbin/itox") {
print STDERR "Suggested entry (automatically converted using
itox):\n\n";
- system("echo $modearg |itox >&2");
+ my $escapedmodearg = $modearg;
+ $escapedmodearg =~ s/'/'\\''/g;
+ system("printf '$escapedmodearg' |itox >&2");
}
print STDERR

}
Not only does this fix the quoting problem, but by using printf instead
of echo it should fix the "\t" escaping issue too.
