Gentoo: GLSA-200401-02: Honeyd remote detection vulnerability via a probe packet
Summary
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gentoo Linux Security Advisory GLSA 200401-02 ~ https://security.gentoo.org/
~ Severity: Low ~ Title: Honeyd remote detection vulnerability via a probe packet ~ Date: January 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.
========== 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 [ 1 ] 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 ========= Users are encouraged to upgrade to honeyd version 0.8:
~ $> emerge sync ~ $> emerge -pv ">=net-analyzer/honeyd-0.8" ~ $> emerge ">=net-analyzer/honeyd-0.8"
