No remote root exploit is currently known. Background ========= Honeyd is a virtual honeypot daemon that can simulate virtual hosts on unallocated IP addresses. 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 [ 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" References ========= ~ [ 1 ] : Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security ofour users machines is of utmost importance to us.
