ver. 0.9.6 (2016/12/10) - stretch-is-coming ----------- 0.9.x line is no longer heavily developed. If you are interested in new features (e.g. IPv6 support), please consider 0.10 branch and its releases. * Misleading add resp. enable of (already available) jail in database, that induced a subsequent error: last position of log file will be never retrieved (gh-795) * Fixed a distribution related bug within testReadStockJailConfForceEnabled (e.g. test-cases faults on Fedora, see gh-1353) * Fixed pythonic filters and test scripts (running via wrong python version, uses "fail2ban-python" now); * Fixed test case "testSetupInstallRoot" for not default python version (also using direct call, out of virtualenv); * Fixed ambiguous wrong recognized date pattern resp. its optional parts (see gh-1512); * FIPS compliant, use sha1 instead of md5 if it not allowed (see gh-1540) * Monit config: scripting is not supported in path (gh-1556) * `filter.d/apache-modsecurity.conf` - Fixed for newer version (one space, gh-1626), optimized: non-greedy catch-all replaced for safer match, unneeded catch-all anchoring removed, non-capturing * `filter.d/asterisk.conf` - Fixed to match different asterisk log prefix (source file: method:) * `filter.d/dovecot.conf` - Fixed failregex ignores failures through some not relevant info (gh-1623) * `filter.d/ignorecommands/apache-fakegooglebot` - Fixed error within apache-fakegooglebot, that will be called with wrong python version (gh-1506) * `filter.d/assp.conf` - Extended failregex and test cases to handle ASSP V1 and V2 (gh-1494) * `filter.d/postfix-sasl.conf` - Allow for having no trailing space after 'failed:' (gh-1497) * `filter.d/vsftpd.conf` - Optional reason part in message after FAIL LOGIN (gh-1543) * `filter.d/sendmail-reject.conf` - removed mandatory double space (if dns-host available, gh-1579) * filter.d/sshd.conf - recognized "Failed publickey for" (gh-1477); - optimized failregex to match all of "Failed any-method for ... from <HOST>" (gh-1479) - eliminated possible complex injections (on user-name resp. auth-info, see gh-1479) - optional port part after host (see gh-1533, gh-1581) * New Actions: - `action.d/npf.conf` for NPF, the latest packet filter for NetBSD * New Filters: - `filter.d/mongodb-auth.conf` for MongoDB (document-oriented NoSQL database engine) (gh-1586, gh-1606 and gh-1607) * DateTemplate regexp extended with the word-end boundary, additionally to word-start boundary * Introduces new command "fail2ban-python", as automatically created symlink to python executable, where fail2ban currently installed (resp. its modules are located): - allows to use the same version, fail2ban currently running, e.g. in external scripts just via replace python with fail2ban-python: ```diff -#!/usr/bin/env python +#!/usr/bin/env fail2ban-python ``` - always the same pickle protocol - the same (and also guaranteed available) fail2ban modules - simplified stand-alone install, resp. stand-alone installation possibility via setup (like gh-1487) is getting closer * Several test cases rewritten using new methods assertIn, assertNotIn * New forward compatibility method assertRaisesRegexp (normally python >= 2.7). Methods assertIn, assertNotIn, assertRaisesRegexp, assertLogged, assertNotLogged are test covered now * Jail configuration extended with new syntax to pass options to the backend (see gh-1408), examples: - `backend = systemd[journalpath=/run/log/journal/machine-1]` - `backend = systemd[journalfiles="/run/log/journal/machine-1/system.journal, /run/log/journal/machine-1/user.journal"]` - `backend = systemd[journalflags=2]` -

ver. 0.9.5 (2016/07/15) - old-not-obsolete ----------- 0.9.x line is no longer heavily developed. If you are interested in new features (e.g. IPv6 support), please consider 0.10 branch and its releases. * `filter.d/monit.conf` - Extended failregex with new monit "access denied" version (gh-1355) - failregex of previous monit version merged as single expression * `filter.d/postfix.conf`, `filter.d/postfix-sasl.conf` - Extended failregex daemon part, matching also `postfix/smtps/smtpd` now (gh-1391) * Fixed a grave bug within tags substitutions because of incorrect detection of recursion in case of multiple inline substitutions of the same tag (affected actions: `bsd-ipfw`, etc). Now tracks the actual list of the already substituted tags (per tag instead of single list) * `filter.d/common.conf` - Unexpected extra regex-space in generic `__prefix_line` (gh-1405) - All optional spaces normalized in `common.conf`, test covered now - Generic `__prefix_line` extended with optional brackets for the date ambit (gh-1421), added new parameter `__date_ambit` * `gentoo-initd` fixed `--pidfile` bug: `--pidfile` is option of `start-stop-daemon`, not argument of fail2ban (see gh-1434) * `filter.d/asterisk.conf` - Fixed security log support for PJSIP and Asterisk 13+ (gh-1456) - Improved log support for PJSIP and Asterisk 13+ with different callID (gh-1458) * New Actions: - `action.d/firewallcmd-rich-rules` and `action.d/firewallcmd-rich-logging` (gh-1367) * New filters: - slapd - ban hosts, that were failed to connect with invalid credentials: error code 49 (gh-1478) * Extreme speedup of all sqlite database operations (gh-1436), by using of following sqlite options: - (synchronous = OFF) write data through OS without syncing - (journal_mode = MEMORY) use memory for the transaction logging - (temp_store = MEMORY) temporary tables and indices are kept in memory * journald journalmatch for pure-ftpd (gh-1362) * Added additional regex filter for dovecot ldap authentication failures (gh-1370) * `filter.d/exim*conf` - Added additional regexes (gh-1371) - Made port entry optional -

ver. 0.9.4 (2016/03/08) - for-you-ladies ----------- - Fixes: * roundcube-auth jail typo for logpath * Fix dnsToIp resolver for fqdn with large list of IPs (gh-1164) * filter.d/apache-badbots.conf - Updated useragent string regex adding escape for `+` * filter.d/mysqld-auth.conf - Updated "Access denied ..." regex for MySQL 5.6 and later (gh-1211, gh-1332) * filter.d/sshd.conf - Updated "Auth fail" regex for OpenSSH 5.9 and later * Treat failed and killed execution of commands identically (only different log messages), which addresses different behavior on different exit codes of dash and bash (gh-1155) * Fix jail.conf.5 man's section (gh-1226) * Fixed default banaction for allports jails like pam-generic, recidive, etc with new default variable `banaction_allports` (gh-1216) * Fixed `fail2ban-regex` stops working on invalid (wrong encoded) character for python version < 3.x (gh-1248) * Use postfix_log logpath for postfix-rbl jail * filters.d/postfix.conf - add 'Sender address rejected: Domain not found' failregex * use `fail2ban_agent` as user-agent in actions badips, blocklist_de, etc (gh-1271) * Fix ignoring the sender option by action_mw, action_mwl and action_c_mwl * Changed filter.d/asterisk regex for "Call from ..." (few vulnerable now) * Removed compression and rotation count from logrotate (inherit them from the global logrotate config) - New Features: * New interpolation feature for definition config readers - `<known/parameter>` (means last known init definition of filters or actions with name `parameter`). This interpolation makes possible to extend a parameters of stock filter or action directly in jail inside jail.local file, without creating a separately filter.d/*.local file. As extension to interpolation `%(known/parameter)s`, that does not works for filter and action init parameters * New actions: - nftables-multiport and nftables-allports - filtering using nftables framework. Note: it requires a pre-existing chain for the filtering rule. * New filters: - openhab - domotic software authentication failure with the rest api and web interface (gh-1223) - nginx-limit-req - ban hosts, that were failed through nginx by limit request processing rate (ngx_http_limit_req_module) - murmur - ban hosts that repeatedly attempt to connect to murmur/mumble-server with an invalid server password or certificate. - haproxy-http-auth - filter to match failed HTTP Authentications against a HAProxy server * New jails: - murmur - bans TCP and UDP from the bad host on the default murmur port. * sshd filter got new failregex to match "maximum authentication attempts exceeded" (introduced in openssh 6.8) * Added filter for Mac OS screen sharing (VNC) daemon - Enhancements: * Do not rotate empty log files * Added new date pattern with year after day (e.g. Sun Jan 23 2005 21:59:59) http://bugs.debian.org/798923 * Added openSUSE path configuration (Thanks Johannes Weberhofer) * Allow to split ignoreip entries by ',' as well as by ' ' (gh-1197) * Added a timeout (3 sec) to urlopen within badips.py action (Thanks M. Maraun) * Added check against atacker's Googlebot PTR fake records (Thanks Pablo Rodriguez Fernandez) * Enhance filter against atacker's Googlebot PTR fake records (gh-1226) * Nginx log paths extended (prefixed with "*" wildcard) (gh-1237) * Added filter for openhab domotic software authentication failure with the rest api and web interface (gh-1223) * Add *_backend options for services to allow distros to set the default backend per service, set default to systemd for Fedora as appropriate * Performance improvements while monitoring large number of files (gh-1265). Use associative array (dict) for monitored log files to speed up lookup operations. Thanks @kshetragia * Specified that fail2ban is PartOf iptables.service firewalld.service in .service file -- would reload fail2ban if those services are restarted * Provides new default `fail2ban_version` and interpolation variable `fail2ban_agent` in jail.conf * Enhance filter 'postfix' to ban incoming SMTP client with no fqdn hostname, and to support multiple instances of postfix having varying suffix (gh-1331) (Thanks Tom Hendrikx) * files/gentoo-initd to use start-stop-daemon to robustify restarting the service
