Gentoo Linux Security Advisory

Title: Honeyd remote detection vulnerability via a probe packet (GLSA 200401-02)
Severity: low
Exploitable: remote
Date: January 21, 2004
Bug(s): #38934
ID: 200401-02

Synopsis


Identification of Honeyd installations allows an adversary to launch
attacks specifically against Honeyd. No remote root exploit is currently
known.


Background


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


Affected Packages

Package: net-analyzer/honeyd
Vulnerable: < 0.8
Unaffected: >= 0.8
Architectures: All supported architectures


Description


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.


Resolution


All users are recommended to update to honeyd version 0.8:
