Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Identification of Honeyd installations allows an adversary to launch |
| 22 |
attacks specifically against Honeyd. No remote root exploit is currently |
| 23 |
known. |
| 24 |
|
| 25 |
Background |
| 26 |
========== |
| 27 |
|
| 28 |
Honeyd is a virtual honeypot daemon that can simulate virtual hosts on |
| 29 |
unallocated IP addresses. |
| 30 |
|
| 31 |
Description |
| 32 |
=========== |
| 33 |
|
| 34 |
A bug in handling NMAP fingerprints caused Honeyd to reply to TCP |
| 35 |
packets with both the SYN and RST flags set. Watching for replies, it is |
| 36 |
possible to detect IP addresses simulated by Honeyd. |
| 37 |
|
| 38 |
Impact |
| 39 |
====== |
| 40 |
|
| 41 |
Although there are no public exploits known for Honeyd, the detection of |
| 42 |
Honeyd IP addresses may in some cases be undesirable. |
| 43 |
|
| 44 |
Workaround |
| 45 |
========== |
| 46 |
|
| 47 |
Honeyd 0.8 has been released along with an advisory [ 1 ] to address |
| 48 |
this issue. In addition, Honeyd 0.8 drops privileges if permitted by the |
| 49 |
configuration file and contains command line flags to force dropping of |
| 50 |
privileges. |
| 51 |
|
| 52 |
Resolution |
| 53 |
========== |
| 54 |
|
| 55 |
Users are encouraged to upgrade to honeyd version 0.8: |
| 56 |
|
| 57 |
~ $> emerge sync |
| 58 |
~ $> emerge -pv ">=net-analyzer/honeyd-0.8" |
| 59 |
~ $> emerge ">=net-analyzer/honeyd-0.8" |
| 60 |
