SUMMARY :buffer overflow |

OVERVIEW |
| 15 |
|
| 16 |
The ISIS protocol dissector in Ethereal 0.9.5 and earlier versions |
| 17 |
is susceptible to a buffer overflow. |
| 18 |
|
| 19 |
DETAIL |
| 20 |
|
| 21 |
It may be possible to make Ethereal crash or hang by injecting a |
| 22 |
purposefully malformed packet onto the wire, or by convincing someone |
| 23 |
to read a malformed packet trace file. It may be possible to make |
| 24 |
Ethereal run arbitrary code by exploiting the buffer and pointer problems. |
| 25 |
|
| 26 |

SOLUTION |
| 30 |
|
| 31 |
It is recommended that all Gentoo Linux users who are running |
| 32 |
net-analyzer/ethereal-0.9.5-r2 and earlier update their systems |
| 33 |
as follows: |
| 34 |
|
| 35 |
emerge rsync |
| 36 |
emerge ethereal |
| 37 |
emerge clean |
| 38 |
