Synopsis |
19 |
======== |
20 |
|
21 |
glFTPd is vulnerable to a local buffer overflow which may allow |
22 |
arbitrary code execution. |
23 |
|
24 |
Background |
25 |
========== |
26 |
|
27 |

Description |
38 |
=========== |
39 |
|
40 |
The glFTPd server is vulnerable to a buffer overflow in the 'dupescan' |
41 |
program. This vulnerability is due to an unsafe strcpy() call which can |
42 |
cause the program to crash when a large argument is passed. |
43 |
|
44 |
Impact |
45 |
====== |
46 |
|
47 |
A local user with malicious intent can pass a parameter to the dupescan |
48 |
program that exceeds the size of the buffer, causing it to overflow. |
49 |
This can lead the program to crash, and potentially allow arbitrary |
50 |
code execution with the permissions of the user running glFTPd, which |
51 |
could be the root user. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
There is no known workaround at this time. |
57 |
|
58 |
Resolution |
59 |
========== |
60 |
|
61 |
All glFTPd users should upgrade to the latest version: |
62 |
|
63 |
# emerge sync |
64 |
|
65 |
# emerge -pv ">=net-ftp/glftpd-1.32-r1" |
66 |
# emerge ">=net-ftp/glftpd-1.32-r1" |
67 |
