Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Cube is vulnerable to a buffer overflow, invalid memory access and |
| 19 |
remote client crashes, possibly leading to a Denial of Service or |
| 20 |
remote code execution. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
Cube is an open source first person shooter game engine supporting |
| 26 |
multiplayer via LAN or internet. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|
| 31 |
------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |
| 34 |
1 games-fps/cube <= 20050829 Vulnerable! |
| 35 |
------------------------------------------------------------------- |
| 36 |
NOTE: Certain packages are still vulnerable. Users should migrate |
| 37 |
to another package if one is available or wait for the |
| 38 |
existing packages to be marked stable by their |
| 39 |
architecture maintainers. |

Description |
| 42 |
=========== |
| 43 |
|
| 44 |
Luigi Auriemma reported that Cube is vulnerable to a buffer overflow in |
| 45 |
the sgetstr() function (CVE-2006-1100) and that the sgetstr() and |
| 46 |
getint() functions fail to verify the length of the supplied argument, |
| 47 |
possibly leading to the access of invalid memory regions |
| 48 |
(CVE-2006-1101). Furthermore, he discovered that a client crashes when |
| 49 |
asked to load specially crafted mapnames (CVE-2006-1102). |
| 50 |
|
| 51 |
Impact |
| 52 |
====== |
| 53 |
|
| 54 |
A remote attacker could exploit the buffer overflow to execute |
| 55 |
arbitrary code with the rights of the user running cube. An attacker |
| 56 |
could also exploit the other vulnerabilities to crash a Cube client or |
| 57 |
server, resulting in a Denial of Service. |
| 58 |
|
| 59 |
Workaround |
| 60 |
========== |
| 61 |
|
| 62 |
Play solo games or restrict your multiplayer games to trusted parties. |
| 63 |
|
| 64 |
Resolution |
| 65 |
========== |
| 66 |
|
| 67 |
Upstream stated that there will be no fixed version of Cube, thus the |
| 68 |
Gentoo Security Team decided to hardmask Cube for security reasons. All |
| 69 |
Cube users are encouraged to uninstall Cube: |
| 70 |
|
| 71 |
# emerge --ask --unmerge games-fps/cube |
| 72 |
|
