Synopsis |
16 |
======== |
17 |
|
18 |
The webapp-config utility insecurely creates temporary files in a world |
19 |
writable directory, potentially allowing the execution of arbitrary |
20 |
commands. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
webapp-config is a Gentoo Linux utility to help manage the installation |
26 |
of web-based applications. |
27 |
|
28 |
Affected packages |
29 |
================= |

Package / Vulnerable / Unaffected |

Description |
37 |
=========== |
38 |
|
39 |
Eric Romang discovered webapp-config uses a predictable temporary |
40 |
filename while processing certain options, resulting in a race |
41 |
condition. |
42 |
|
43 |
Impact |
44 |
====== |
45 |
|
46 |
Successful exploitation of the race condition would allow an attacker |
47 |
to disrupt the operation of webapp-config, or execute arbitrary shell |
48 |
commands with the privileges of the user running webapp-config. A local |
49 |
attacker could use a symlink attack to create or overwrite files with |
50 |
the permissions of the user running webapp-config. |
51 |
|
52 |
Workaround |
53 |
========== |
54 |
|
55 |
There is no known workaround at this time. |
56 |
|
57 |
Resolution |
58 |
========== |
59 |
|
60 |
All webapp-config users should upgrade to the latest version: |
61 |
|
62 |
# emerge --sync |
63 |
# emerge --ask --oneshot --verbose ">=net-www/webapp-config-1.11" |
64 |
