Synopsis |
16 |
======== |
17 |
|
18 |
A flaw in ProFTPD may allow a local attacker to obtain root privileges. |
19 |
|
20 |
Background |
21 |
========== |
22 |
|
23 |
ProFTPD is a powerful, configurable, and free FTP daemon. |
24 |
|

Package / Vulnerable / Unaffected |

------------------------------------------------------------------- |
31 |
1 net-ftp/proftpd < 1.3.1_rc1 >= 1.3.1_rc1 |
32 |
|
33 |
Description |
34 |
=========== |
35 |
|
36 |
A flaw exists in the mod_ctrls module of ProFTPD, normally used to |
37 |
allow FTP server administrators to configure the daemon at runtime. |
38 |
|
39 |
Impact |
40 |
====== |
41 |
|
42 |
An FTP server administrator permitted to interact with mod_ctrls could |
43 |
potentially compromise the ProFTPD process and execute arbitrary code |
44 |
with the privileges of the FTP Daemon, which is normally the root user. |
45 |
|
46 |
Workaround |
47 |
========== |
48 |
|
49 |
Disable mod_ctrls, or ensure only trusted users can access this |
50 |
feature. |
51 |
|
52 |
Resolution |
53 |
========== |
54 |
|
55 |
All ProFTPD users should upgrade to the latest version: |
56 |
|
57 |
# emerge --sync |
58 |
# emerge --ask --oneshot --verbose ">=net-ftp/proftpd-1.3.1_rc1" |
