Synopsis |
17 |
======== |
18 |
|
19 |
Automake may be vulnerable to a symbolic link attack which may allow an |
20 |
attacker to modify data or elevate their privileges. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
Automake is a tool for automatically generating `Makefile.in' files |
26 |
which is often used in conjuction with Autoconf and other GNU Autotools |
27 |
to ease portability among applications. It also provides a standardized |
28 |
and light way of writing complex Makefiles through the use of many |
29 |
built-in macros. |

Description |
40 |
=========== |
41 |
|
42 |
Automake may be vulnerable to a symbolic link attack which may allow an |
43 |
attacker to modify data or escalate their privileges. This is due to |
44 |
the insecure way Automake creates directories during compilation. An |
45 |
attacker may be able to create symbolic links in the place of files |
46 |
contained in the affected directories, which may potentially lead to |
47 |
elevated privileges due to modification of data. |
48 |
|
49 |
Impact |
50 |
====== |
51 |
|
52 |
An attacker may be able to use this vulnerability to modify data in an |
53 |
unauthorized fashion or elevate their privileges. |
54 |
|
55 |
Workaround |
56 |
========== |
57 |
|
58 |
A workaround is not currently known for this issue. All users are |
59 |
advised to upgrade to the latest version of the affected package. |
60 |
|
61 |
Resolution |
62 |
========== |
63 |
|
64 |
Automake users should upgrade to version 1.8.3 or later: |
65 |
|
66 |
# emerge sync |
67 |
|
68 |
# emerge -pv ">=sys-devel/automake-1.8.3" |
69 |
# emerge ">=sys-devel/automake-1.8.3" |
