Fail2Ban (version 0.8.12.dev) 2013/11/13
================================================================================
ver. 0.8.12 (2013/12/XX) - things-can-only-get-better
-----------
- IMPORTANT incompatible changes:
- Fixes:
- Rename firewall-cmd-direct-new to firewall-cmd-new to fit within jail name
name length. As per gh-395
- allow for ",milliseconds" in the custom date format of proftpd.log
- allow for ", referer ..." in apache-* filter for apache error logs.
- allow for spaces at the beginning of kernel messages. Closes gh-448
- recidive jail to block all protocols. Closes gh-440. Thanks Ioan Indreias
- smtps not a IANA standard and has been removed from Arch. Replaced with
465. Thanks Stefan. Closes gh-447
- mysqld-syslog-iptables rule was too long. Part of gh-447.
- add 'flushlogs' command to allow logrotation without clobbering logtarget
settings. Closes gh-458, Debian bug #697333, Redhat bug #891798.
- complain action - ensure where not matching other IPs in log sample.
Closes gh-467
- Fix firewall-cmd actioncheck - patch from Adam Tkac. Redhat Bug #979622
- Enhancements:
- long names on jails documented based on iptables limit of 30 less
len("fail2ban-").
- remove indentation of name and loglevel while logging to SYSLOG to
resolve syslog(-ng) parsing problems. Closes Debian bug #730202.
- added squid filter. Thanks Roman Gelfand.
- New Features:
Daniel Black
* filter.d/solid-pop3d -- added thanks to Jacques Lav!gnotte on mailinglist.
- Enhancements:
- loglines now also report "[PID]" after the name portion
ver. 0.8.11 (2013/11/13) - loves-unittests-and-tight-DoS-free-filter-regexes
-----------
In light of CVE-2013-2178 that triggered our last release we have put
a significant effort into tightening all of the regexs of our filters
to avoid another similar vulnerability. All filters have been updated
and some to catch more login/authentication failures and to support
for newer application versions. There are test cases for most log
cases of failures now.
As usual, if you have other examples that demonstrate that a filter is
insufficient, or if we have inadvertently introduced a regression,
please provide us with example log lines on the github issue tracker
http://github.com/fail2ban/fail2ban/issues and NOT on a random blog in
some obscure corner of the Internet.
Many thanks to our contributors for this release Daniel Black, Yaroslav
Halchenko, Steven Hiscocks, Mark McKinstry, Andy Fragen, Orion Poplawski,
Alexander Dietrich, JP Espinosa, Jamyn Shanley, Beau Raines, François
Boulogne and others who have helped on IRC and mailing list, logged issues
and bug requests.
- IMPORTANT incompatible changes:
Filter name changes:
* 'lighttpd-fastcgi' filter has been renamed to 'suhosin'
* 'sasl' has been renamed to 'postfix-sasl'
* 'exim' spam catching failregexes was split out into 'exim-spam'
These changes will require changing jail.{conf,local} if any of
those filters were used.
- Fixes:
Jonathan Lanning
* filter.d/asterisk -- identified another regex for blocking. Also channel
ID is hex not decimal as noted in sample logs provided.
Daniel Black & Marcel Dopita
* filter.d/apache-auth -- fixed and apache auth samples provide. Closes gh-286
Yaroslav Halchenko
* filter.d/common.conf -- make colon after [daemon] optional. Closes gh-267
* filter.d/apache-common.conf -- support apache 2.4 more detailed error
log format. Closes gh-268
* Backends changes detection and parsing. Close gh-223 and gh-103:
- Polling backend: detect changes in the files not only based on
mtime, but also on the size and inode. It should allow for
better detection of changes and log rotations on busy servers,
older python 2.4, and file systems with precision of mtime only
up to a second (e.g. ext3).
- All backends, possible race condition: do not read from a file
initially reported empty. Originally could have lead to
accounting for detected log lines multiple times.
- Do not crash if executing a command in fail2ban-client interactive
mode has failed (e.g. due to incorrect syntax). Closes gh-353
Daniel Black & Мернов Георгий
* filter.d/dovecot.conf -- Fix when no TLS enabled - line doesn't end in ,
Daniel Black & Georgiy Mernov & ftoppi & Мернов Георгий
* filter.d/exim.conf -- regex hardening and extra failure examples in
sample logs
* filter.d/named-refused.conf - BIND 9.9.3 regex changes
Daniel Black & Sebastian Arcus
* filter.d/asterisk -- more regexes
Daniel Black
* action.d/hostsdeny -- NOTE: new dependancy 'ed'. Switched to use 'ed' across
all platforms to ensure permissions are the same before and after a ban.
Closes gh-266. hostsdeny supports daemon_list now too.
* action.d/bsd-ipfw - action option unsed. Change blocktype to port unreach
instead of deny for consistancy.
* filter.d/dovecot - added to support different dovecot failure
"..disallowed plaintext auth". Closes Debian bug #709324
* filter.d/roundcube-auth - timezone offset can be positive or negative
* action.d/bsd-ipfw - action option unsed. Fixed to blocktype for
consistency. default to port unreach instead of deny
* filter.d/dropbear - fix regexs to match standard dropbear and the patched
http://www.unchartedbackwaters.co.uk/files/dropbear/dropbear-0.52.patch
and add PAM is it in dropbear-2013.60 source code.
* filter.d/{asterisk,assp,dovecot,proftpd}.conf -- regex hardening
and extra failure examples in sample logs
* filter.d/apache-auth - added expressions for mod_authz, mod_auth and
mod_auth_digest failures.
* filter.d/recidive -- support f2b syslog target and anchor regex at start
* filter.d/mysqld-auth.conf - mysql can use syslog
* filter.d/sshd - regex enhancements to support openssh-6.3. Closes Debian
bug #722970. Thanks Colin Watson for the regex analysis.
* filter.d/wuftpd - regex enhancements to support pam and wuftpd. Closes
Debian bug #665925
Rolf Fokkens
* action.d/dshield.conf and complain.conf -- reorder mailx arguments.
https://bugzilla.redhat.com/show_bug.cgi?id=998020
John Doe (ache)
* action.d/bsd-ipfw.conf - invert actionstop logic to make exist status 0.
Closes gh-343.
JP Espinosa (Reviewed by O.Poplawski)
* files/redhat-initd - rewritten to use stock init.d functions thus
avoiding problems with getpid. Also $network and iptables moved
to Should- rc init fields
Rick Mellor
* filter.d/vsftp - fix capture with tty=ftp
- New Features:
Edgar Hoch
* action.d/firewall-cmd-direct-new.conf - action for firewalld
from https://bugzilla.redhat.com/show_bug.cgi?id=979622
NOTE: requires firewalld-0.3.8+
Andy Fragen and Daniel Black
* filter.d/osx-ipfw.conf - ipfw action for OSX based on random rule
numbers.
Anonymous:
* action.d/osx-afctl - an action based on afctl for osx
Daniel Black & ykimon
* filter.d/3proxy.conf -- filter added
* fail2ban-regex - now generates http://www.debuggex.com urls for debugging
regular expressions with the -D parameter.

with additions for greater control over filtering spam.
* add date expression for apache-2.4 - milliseconds
* filter.d/nginx-http-auth -- filter added for http basic authentication
failures in nginx. Partially fulfills gh-405.
Christophe Carles & Daniel Black
* filter.d/perdition.conf -- filter added
Mark McKinstry
* action.d/apf.conf - add action for Advanced Policy Firewall (apf)
Amir Caspi and kjohnsonecl
* filter.d/uwimap-auth - filter for uwimap-auth IMAP/POP server
Steven Hiscocks and Daniel Black
* filter.d/selinux-{common,ssh} -- add SELinux date and ssh filter
- Enhancements:
François Boulogne and Frédéric
* filter.d/lighttpd - auth regexs for lighttpd-1.4.31
Daniel Black
* reorder parsing of jail.conf, jail.d/*.conf, jail.local, jail.d/*.local
and likewise for fail2ban.{conf|local|d/*.conf|d/*.local}. Closes gh-392
* jail.conf now has asterisk jail - no need for asterisk-tcp and
asterisk-udp. Users should replace existing jails with asterisk to
reduce duplicate parsing of the asterisk log file.

- Multithreading. Each jail has its own threads: one for the log reading and
another for the actions
- Execute several actions
- Split configuration files. They are more readable and easy to use
- failregex uses group (<host>) now. This feature was already present in the
Debian package
- lots of things...

feature (-1 is perfect). Thanks to Mannone

network.
- Robust startup: if iptables module does not get fully initialized after
startup of fail2ban, fail2ban will do "maxreinit" attempts to initialize its
own firewall. It will sleep between attempts for "polltime" number of seconds
(closes Debian: #334272). Thanks to Yaroslav Halchenko
- Added "interpolations" in fail2ban.conf. This is provided by the ConfigParser
module. Old configuration files still work. Thanks to Yaroslav Halchenko
- Added initial support for hosts.deny and shorewall. Need more testing. Please
test. Thanks to kojiro from Gentoo forum for hosts.deny support

* Added -f command line parameter for [findtime].
* Added a cleanup of firewall rules on emergency shutdown when unknown
exception is catched.
* Fail2ban should not crash now if a wrong file name is specified in config.
* reordered code a bit so that log targets are setup right after background
and then only loglevel (verbose, debug) is processed, so the warning could
be seen in the logs
* Added a keyword <section> in parsing of the subject and the body of an email
sent out by fail2ban (closes: #330311)
ver. 0.5.4 (2005/09/13) - beta

"failed" log entries
