Honeyd remote detection vulnerability via a probe packet Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200401-02 (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 rights if permitted by the configuration file and contains command line flags to force dropping of rights. References: http://www.honeyd.org/adv.2004-01.asc Solution: 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" Network Security Threat Level: Low Networks Security ID: Vulnerability Assessment Copyright: (C) 2005 Michel Arboi |
