Synopsis |
17 |
======== |
18 |
|
19 |
The login program included in util-linux could leak sensitive |
20 |
information under certain conditions. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
Util-linux is a suite of essential system utilites, including login, |
26 |
agetty, fdisk. |
27 |
|
28 |
Affected packages |
29 |
================= |
30 |
|
31 |
------------------------------------------------------------------- |
32 |
Package / Vulnerable / Unaffected |
33 |
------------------------------------------------------------------- |
34 |
sys-apps/util-linux <= 2.11 >= 2.12 |
35 |
|
36 |
Description |
37 |
=========== |
38 |
|
39 |
In some situations the login program could leak sensitive data due to |
40 |
an incorrect usage of a reallocated pointer. |
41 |
|
42 |
NOTE: Only users who have PAM support disabled on their systems (i.e. -PAM in |
43 |
their USE variable) will be affected by this vulnerability. By default, this |
44 |
USE flag is enabled on all architectures. Users with PAM support on their |
45 |
system receive login binaries as part of the pam-login package, which remains |
46 |
unaffected. |
47 |
|
48 |
Impact |
49 |
====== |
50 |
|
51 |
A remote attacker may obtain sensitive data. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
A workaround is not currently known for this issue. All users are advised to |
57 |
upgrade to the latest version of the affected package. |
58 |
|
59 |
Resolution |
60 |
========== |
61 |
|
62 |
All util-linux users should upgrade to version 2.12 or later: |
63 |
|
64 |
# emerge sync |
65 |
|
66 |
# emerge -pv ">=sys-apps/util-linux-2.12" |
67 |
# emerge ">=sys-apps/util-linux-2.12" |
68 |
