OVERVIEW |
| 15 |
|
| 16 |
possible DoS attack by a special crafted TAR archive file |
| 17 |
|
| 18 |
DETAIL |
| 19 |
|
| 20 |
The AMaViS shell script version (AMaViS 0.1.x / 0.2.x) uses securetar. |
| 21 |
securetar removes the pathes of files in a tar archive and makes each |
| 22 |
file name a unique name. Links, character devices, block devices and named |
| 23 |
pipes will be removed from the archive. |
| 24 |
A special-crafted TAR file may hung securetar forever, using up to |
| 25 |
100% CPU time. |
