Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
DokuWiki is vulnerable to shell command injection and Denial of Service |
| 19 |
attacks when using ImageMagick. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
DokuWiki is a wiki targeted at developer teams, workgroups and small |
| 25 |
companies. It does not use a database backend. |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Input validation flaws have been discovered in the image handling of |
| 39 |
fetch.php if ImageMagick is used, which is not the default method. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
A remote attacker could exploit the flaws to execute arbitrary shell |
| 45 |
commands with the rights of the web server daemon or cause a Denial of |
| 46 |
Service. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All DokuWiki users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=www-apps/dokuwiki-20060309e" |
