Synopsis |
17 |
======== |
18 |
|
19 |
Scorched 3D is vulnerable to a format string attack in the chat box |
20 |
that leads to Denial of Service on the game server and possibly allows |
21 |
execution of arbitrary code. |
22 |
|
23 |
Background |
24 |
========== |
25 |
|
26 |
Scorched 3D is a game based loosely on the classic DOS game "Scorched |
27 |
Earth". Scorched 3D adds amongst other new features a 3D island |
28 |
environment and LAN and internet play. Scorched 3D is totally free and |
29 |
is available for multiple operating systems. |

Description |
40 |
=========== |
41 |
|
42 |
Scorched 3D (build 36.2 and before) does not properly check the text |
43 |
entered in the Chat box (T key). Using format string characters, you |
44 |
can generate a heap overflow. This and several other unchecked buffers |
45 |
have been corrected in the build 37 release. |
46 |
|
47 |
Impact |
48 |
====== |
49 |
|
50 |
This vulnerability can be easily exploited to remotely crash the |
51 |
Scorched 3D server, disconnecting all clients. It could also |
52 |
theorically be used to execute arbitrary code on the server with the |
53 |
rights of the user running the server. |
54 |
|
55 |
Workaround |
56 |
========== |
57 |
|
58 |
A workaround is not currently known for this issue. All users are |
59 |
advised to upgrade to the latest version of the affected package. |
60 |
|
61 |
Resolution |
62 |
========== |
63 |
|
64 |
Scorched 3D users should upgrade to version 37 or later: |
65 |
|
66 |
# emerge sync |
67 |
|
68 |
# emerge -pv ">=games-strategy/scorched3d-37" |
69 |
# emerge ">=games-strategy/scorched3d-37" |
