15 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"
