Synopsis |
| 20 |
======== |
| 21 |
|
| 22 |
Game servers based on the Unreal engine are vulnerable to remote code |
| 23 |
execution through malformed 'secure' queries. |
| 24 |
|
| 25 |
Background |
| 26 |
========== |
| 27 |
|
| 28 |
Unreal Tournament 2003 and 2004 are popular first-person-shooter games. |
| 29 |
They are both based on the Unreal engine, and can be used in a game |
| 30 |
server / client setup. |
| 31 |

Description |
| 47 |
=========== |
| 48 |
|
| 49 |
The Unreal-based game servers support a specific type of query called |
| 50 |
'secure'. Part of the Gamespy protocol, this query is used to ask if |
| 51 |
the game server is able to calculate an exact response using a provided |
| 52 |
string. Luigi Auriemma found that sending a long 'secure' query |
| 53 |
triggers a buffer overflow in the game server. |
| 54 |
|
| 55 |
Impact |
| 56 |
====== |
| 57 |
|
| 58 |
By sending a malicious UDP-based 'secure' query, an attacker could |
| 59 |
execute arbitrary code on the game server. |
| 60 |
|
| 61 |
Workaround |
| 62 |
========== |
| 63 |
|
| 64 |
Users can avoid this vulnerability by not using Unreal Tournament to |
| 65 |
host games as a server. All users running a server should upgrade to |
| 66 |
the latest versions. |
| 67 |
|
| 68 |
Resolution |
| 69 |
========== |
| 70 |
|
| 71 |
All Unreal Tournament users should upgrade to the latest available |
| 72 |
versions: |
| 73 |
|
| 74 |
# emerge sync |
| 75 |
|
| 76 |
# emerge -pv ">=games-fps/ut2003-2225-r3" |
| 77 |
# emerge ">=games-fps/ut2003-2225-r3" |
| 78 |
|
| 79 |
# emerge -pv ">=games-server/ut2003-ded-2225-r2" |
| 80 |
# emerge ">=games-server/ut2003-ded-2225-r2" |
| 81 |
|
| 82 |
# emerge -pv ">=games-fps/ut2004-3236" |
| 83 |
# emerge ">=games-fps/ut2004-3236" |
| 84 |
|
| 85 |
# emerge -pv ">=games-fps/ut2004-demo-3120-r4" |
| 86 |
# emerge ">=games-fps/ut2004-demo-3120-r4" |
