(Honeyd remote detection vulnerability via a probe packet)

    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.
  
Impact :

    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."
