Synopsis |
16 |
======== |
17 |
|
18 |
Two separate vulnerabilities have been found in Nexuiz allowing the |
19 |
remote execution of arbitrary code and a Denial of Service. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Nexuiz is a multi-player FPS game which uses a modified version of the |
25 |
Quake 1 engine. |
26 |
|
27 |
Affected packages |
28 |
================= |
29 |
|
30 |
------------------------------------------------------------------- |
31 |
Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 games-fps/nexuiz < 2.2.1 >= 2.2.1 |
34 |
|
35 |
Description |
36 |
=========== |
37 |
|
38 |
Nexuiz fails to correctly validate input within "clientcommands". There |
39 |
is also a failure to correctly handle connection attempts from remote |
40 |
hosts. |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
Using a specially crafted "clientcommand" a remote attacker can cause a |
46 |
buffer overflow in Nexuiz which could result in the execution of |
47 |
arbitrary code. Additionally, there is a Denial of Service |
48 |
vulnerability in Nexuiz allowing an attacker to cause Nexuiz to crash |
49 |
or to run out of resources by overloading it with specially crafted |
50 |
connection requests. |
51 |
|
52 |
Workaround |
53 |
========== |
54 |
|
55 |
There is no known workaround at this time. |
56 |
|
57 |
Resolution |
58 |
========== |
59 |
|
60 |
All Nexuiz users should upgrade to the latest version: |
61 |
|
62 |
# emerge --sync |
63 |
# emerge --ask --oneshot --verbose ">=games-fps/nexuiz-2.2.1" |
64 |
