- From leafnode advisory: |
| 16 |
|
| 17 |
"This vulnerability can make leafnode's nntpd server, named leafnode, go |
| 18 |
into an unterminated loop when a particular article is requested. The |
| 19 |
connection becomes irresponsive, and the server hogs the CPU. The client |
| 20 |
will have to terminate the connection and connect again, and may fall |
| 21 |
prey to the same problem; ultimately, there may be so many leafnode |
| 22 |
processes hogging the CPU that no serious work is possible any more and |
| 23 |
the super user has to kill all running leafnode processes." |
