Synopsis |
16 |
======== |
17 |
|
18 |
Links does not properly validate "smb://" URLs, making it vulnerable to |
19 |
the execution of arbitrary Samba commands. |
20 |
|
21 |
Background |
22 |

Description |
35 |
=========== |
36 |
|
37 |
Teemu Salmela discovered that Links does not properly validate "smb://" |
38 |
URLs when it runs smbclient commands. |
39 |
|
40 |
Impact |
41 |
====== |
42 |
|
43 |
A remote attacker could entice a user to browse to a specially crafted |
44 |
"smb://" URL and execute arbitrary Samba commands, which would allow |
45 |
the overwriting of arbitrary local files or the upload or the download |
46 |
of arbitrary files. This vulnerability can be exploited only if |
47 |
"smbclient" is installed on the victim's computer, which is provided by |
48 |
the "samba" Gentoo package. |
49 |
|
50 |
Workaround |
51 |
========== |
52 |
|
53 |
There is no known workaround at this time. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All Links users should upgrade to the latest version: |
59 |
|
60 |
# emerge --sync |
61 |
# emerge --ask --oneshot --verbose ">=www-client/links-2.1_pre26" |
62 |
