OVERVIEW |
| 15 |
|
| 16 |
A remote user may be able to gain root access to an OpenAFS database |
| 17 |
server or fileserver host. In addition, certain administrative clients |
| 18 |
may be attacked if they make requests to a rogue server. |
| 19 |
|
| 20 |
DETAIL |
| 21 |
|
| 22 |
There is an integer overflow bug in the SUNRPC-derived RPC library |
| 23 |
used by OpenAFS that could be exploited to crash certain OpenAFS |
| 24 |
servers (volserver, vlserver, ptserver, buserver) or to obtain |
| 25 |
unauthorized root access to a host running one of these processes. |
| 26 |
|
| 27 |
In addition, it is possible for a rogue server to attack certain |
| 28 |
administrative clients (vos, pts, backup, butc, rxstat), but only |
| 29 |
if certain RPC requests are made to the rogue server. |
| 30 |
|
| 31 |
The OpenAFS fileserver and cache manager (client) are not vulnerable |
| 32 |
to these attacks. No exploits are presently known to be available |
| 33 |
for this vulnerability. |
| 34 |
