Fail2Ban (version 0.8.11.pre1) 2013/10/30
|
|
================================================================================
|
|
|
|
ver. 0.8.11 (2013/11/XXX) - 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
|
|
include more failure regexs supporting previously unbanned failures and
|
|
support for newer application versions too. 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 please give us an example log line on the github issue tracker
|
|
http://github.com/fail2ban/fail2ban/issues and NOT on a random blog in some
|
|
obscure corner of the Internet.
|
|
|
|
During the tightening of the regexs to avoid DoS vulnerabilities there is the
|
|
possibility that we have inadvertently, despite our best intentions,
|
|
incorrectly allowed a failure to continue. We will fix this as quickly as
|
|
humanly possible.
|
|
|
|
IMPORTANT incompatible changes:
|
|
Filter name changes:
|
|
* 'lighttpd-fastcgi' filter has been renamed to 'suhosin'
|
|
* 'sasl' has been renamed to 'postfix-sasl'
|
|
These will require changing in jail.{conf,local} if using these filters.
|
|
Exim filter has been split into an spam and a relay/auth filter.
|
|
|
|
- Fixes:
|
|
Daniel Black & Marcel Dopita
|
|
* filter.d/apache-auth -- fixed and apache auth samples provide. closes #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
|

ver. 0.7.0 (2006/08/23) - alpha
|
|
----------
|
|
- Almost a complete rewrite :) Fail2ban design is really better (IMHO). There is
|
|
a lot of new features
|
|
- Client/Server architecture
|
|
- 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...
|
|
|
|
ver. 0.6.1 (2006/03/16) - stable

|

|
|
Börjesson
|
|
- Removed 192.168.0.0/16 from ignoreip. Attacks could also come from the local
|
|
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
|
|

|
|
test. Thanks to kojiro from Gentoo forum for hosts.deny support

|
|
ver. 0.5.5 (2005/10/26) - beta
|
|
----------
|
|
- Propagated patches introduced by Debian maintainer (Yaroslav Halchenko):
|
|
* Introduced fwcheck option to verify consistency of the chains. Implemented
|
|
automatic restart of fail2ban main function in case check of fwban or
|
|
fwunban command failed (closes: #329163, #331695). (Introduced patch was
|
|
further adjusted by upstream author).
|
|
* 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)
|
|
|
|
