![]() ![]() This just clarifies that the derivative works definition and all other license clauses only apply to parties who choose to accept the license in return for the special rights granted (such as Nmap redistribution rights). Updated the Nmap Public Source License (NPSL) to Version 0.95. This only affects port scans and OS detection scans, since NSE and version scan do not rely on timing data to adjust speed. Periodically reset the system idle timer to keep the system from going to sleep while scans are in process. Dramatically speed up Ncat transfers on Windows Updates to the Japanese manpage translation ![]() Fix mpint packing in ssh2 library, which was causing OpenSSH errors like "ssh_dispatch_run_fatal: bignum is negative" Improved DNS domain name parsing to avoid recursion and enforce name length limits, avoiding a theoretical stack overflow issue with certain crafted DNS server responses, reported Addressed an issue from the Debian bug tracker Handle Internationalized Domain Names (IDN) like ?.? on platforms where getaddrinfo supports the AI_IDN flag Ncat in listen mode with -udp -ssl will use DTLS to secure incoming connections The DTLSSessionReq probe has had its rarity lowered to 2 to allow it to be sent sooner in the scan Nmap's service scan (-sV) can now probe the UDP service behind a DTLS tunnel, the same as it already does for TCP services with SSL/TLS encryption. Port scan responses will be used to kick-start the version matching process Previously, the nmap-payloads file was used for port scan. UDP port scan (-sU) and version scan (-sV) now both use the same data source, nmap-service-probes, for data payloads. Removed the bogus OpenSSL message from the Windows Nmap executable which looked like "NSOCK ERROR ssl_init_helper(): OpenSSL legacy provider failed to load." We actually already have the legacy provider built-in to our OpenSSL builds, and that's why loading the external one fails. Upgrade included libraries: zlib 1.2.13, Lua 5.4.4, libpcap 1.10.4 This resolves some CVE's (CVE-2022-3602 CVE-2022-3786) which don't impact Nmap proper since it doesn't do certificate validation, but could possibly impact Ncat when the -ssl-verify option is used. Upgraded OpenSSL binaries (for the Windows builds and for RPM's) to version 3.0.8. This also enables -broker and -chat via UDP Ncat can now accept "connections" from multiple UDP hosts in listen mode with the -keep-open option. dded the tftp-version script which requests a nonexistent file from a TFTP server and matches the error message to a database of known software Added 22 fingerprints, bringing the new total to 5700! Integrated many of the most-submitted IPv4 OS fingerprints for recent versions of Windows, iOS, macOS, Linux, and BSD. ![]() Overhauled Nmap's string interning and several other startup-related procedures to speed up start times, especially for scans using OS detection Lots of profile-guided memory and processing improvements for Nmap, including OS fingerprint matching, probe matching and retransmission lookups for large hostgroups, and service name lookups. This is similar to how the Wireshark installer works and is particularly helpful for organizations that want to fully automate their Nmap (and Npcap) deployments. Now with the /S option, Nmap checks whether Npcap is already installed (either the free version or OEM) and will silently install itself if so. It previously didn't offer silent mode (/S) because the free/demo version of Npcap Windoes packet capturing driver that it needs and ships with doesn't include a silent installer. Added partial silent-install support to the Nmap Windows installer. Nmap now prints vendor names based on MAC address for MA-S (24-bit), MA-M (28-bit), and MA-L (36-bit) registrations instead of the fixed 3-byte MAC prefix used previously for lookups. It includes dozens of performance improvements, bug fixes and feature enhancements described at Upgraded Npcap (our Windows raw packet capturing and transmission driver) from version 1.71 to the latest version 1.75. Updated Zenmap to Python 3 and PyGObject Zenmap and Ndiff now use Python 3! Thanks to the many contributors who made this effort possible: ![]()
