GLSA 200401-02: Honeyd remote detection vulnerability via a probe packet

Severity:	low
Title:	Honeyd remote detection vulnerability via a probe packet
Date:	01/21/2004
Bugs:	#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	Vulnerable	Unaffected	Architecture(s)
net-analyzer/honeyd	< 0.8	>= 0.8	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:

    $> emerge sync
    $> emerge -pv ">=net-analyzer/honeyd-0.8"
    $> emerge ">=net-analyzer/honeyd-0.8"
