15 Synopsis
16 ========
17
18 gtkdiskfree is vulnerable to symlink attacks, potentially allowing a
19 local user to overwrite arbitrary files.
20
21 Background
22 ==========
23
24 gtkdiskfree is a GTK-based GUI to show free disk space.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 app-admin/gtkdiskfree < 1.9.3-r1 >= 1.9.3-r1
33
34 Description
35 ===========
36
37 Eric Romang discovered that gtkdiskfree insecurely creates a
38 predictable temporary file to handle command output.
39
40 Impact
41 ======
42
43 A local attacker could create a symbolic link in the temporary files
44 directory, pointing to a valid file somewhere on the filesystem. When
45 gtkdiskfree is executed, this would result in the file being
46 overwritten with the rights of the user running the application.
47
48 Workaround
49 ==========
50
51 There is no known workaround at this time.
52
53 Resolution
54 ==========
55
56 All gtkdiskfree users should upgrade to the latest version:
57
58 # emerge --sync
59 # emerge --ask --oneshot --verbose ">=app-admin/gtkdiskfree-1.9.3-r1"
