Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Venustech AD-LAB discovered that an FTP client connected to a |
| 38 |
vulnerable server with passive mode and SSL support can trigger an |
| 39 |
fclose() function call on an uninitialized stream in ftpd.c. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
A remote attacker can send specially crafted FTP data to a server with |
| 45 |
passive mode and SSL support, causing the ftpd daemon to crash. |
| 46 |
|
| 47 |
Workaround |
| 48 |
========== |
| 49 |
|
| 50 |
Disable passive mode or SSL. |
| 51 |
|
| 52 |
Resolution |
| 53 |
========== |
| 54 |
|
| 55 |
All Netkit FTP Server users should upgrade to the latest version: |
| 56 |
|
| 57 |
# emerge --sync |
| 58 |
# emerge --ask --oneshot --verbose ">=net-ftp/netkit-ftpd-0.17-r7" |
