Synopsis |
16 |
======== |
17 |
|
18 |
Multiple vulnerabilities in the way sysstat handles symlinks may allow |
19 |
an attacker to execute arbitrary code or overwrite arbitrary files |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
sysstat is a package containing a number of performance monitoring |
25 |
utilities for Linux, including sar, mpstat, iostat and sa tools |
26 |
|
27 |
Affected packages |
28 |
================= |
29 |
|
30 |
------------------------------------------------------------------- |
31 |
Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
app-admin/sysstat < 5.0.2 >= 5.0.2 |
34 |
|
35 |
Description |
36 |
=========== |
37 |
|
38 |
There are two vulnerabilities in the way sysstat handles symlinks: |
39 |
|
40 |
1. The isag utility, which displays sysstat data in a graphical |
41 |
format, creates a temporary file in an insecure manner. |
42 |
|
43 |
2. Two scripts in the sysstat package, post and trigger, create |
44 |
temporary files in an insecure manner. |
45 |
|
46 |
Impact |
47 |
====== |
48 |
|
49 |
Both vulnerabilities may allow an attacker to overwrite arbitrary files |
50 |
under the permissions of the user executing any of the affected |
51 |
utilities. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
A workaround is not currently known for this issue. All users are |
57 |
advised to upgrade to the latest version of the affected package. |
58 |
|
59 |
Resolution |
60 |
========== |
61 |
|
62 |
Systat users should upgrade to version 4.2 or later: |
63 |
|
64 |
# emerge sync |
65 |
|
66 |
# emerge -pv ">=app-admin/sysstat-5.0.2" |
67 |
# emerge ">=app-admin/sysstat-5.0.2" |
68 |
