Honeyd is a virtual honeypot daemon that can simulate virtual hosts on
|
|
unallocated IP addresses.

|
|
A bug in handling NMAP fingerprints caused Honeyd to reply to TCP
|
|
packets with both the SYN and RST flags set. Watching for replies, it is
|
|
possible to detect IP addresses simulated by Honeyd.

Although there are no public exploits known for Honeyd, the detection
|
|
of Honeyd IP addresses may in some cases be undesirable.

<workaround>

|
|
Honeyd 0.8 has been released along with an advisory to address this
|
|
issue. In addition, Honeyd 0.8 drops privileges if permitted by the
|
|
configuration file and contains command line flags to force dropping
|
|
of privileges.
|
|
</p>

All users are recommended to update to honeyd version 0.8:
|
|
</p>
|
|
<code>
|
|
$> emerge sync
|
|
$> emerge -pv ">=net-analyzer/honeyd-0.8"
|
|
$> emerge ">=net-analyzer/honeyd-0.8"</code>
