This is a HUGE bump, so look at the changelog on the Snort website !
For example, Snort does not natively handle MySQL anymore.
As for the pkgsrc changes :
- updated deps (net/daq) ;
- updated config files ;
- updated MASTER_SITE ;
- some substitution to handle pkgsrc paths ;
- updated compile options.
If you are using this package make note of the distribution change
mentioned below. I have update the MESSAGE to inform users of this and
there is now also a net/snort-rules package with the community rules.
> [*] Distribution Change
> * Rules are no longer distributed as part of the Snort releases, they are
> available as a separate download from snort.org. This was done for
> three reasons:
> 1) To better manage the new rules licensing.
> 2) To reduce the size of the engine download.
> 3) To move the thousands of documentation files for the rules into
> the rules tarballs. If you've ever checked Snort out of CVS you'll
> know why this is a Good Thing.
>
> [*] New additions
> * Added new IP defragmentation preprocessor, Frag3. The frag3 preprocessor
> is a target-based IP defragmentation module, and is intended as a
> replacement for the frag2 module. Check out the README.frag3 for full
> info on this new preprocessor.
>
> * Libprelude support has been added (enable with --enable-prelude).
> Thanks Yoann Vandoorselaere!
>
> * An "ftpbounce" rule detection plugin was added for easier detection of
> FTP bounce attacks.
>
> * Added a new Snort config option, "ignore_ports," to ignore packets
> based on port number. This is similar to bpf filters, but done within
> snort.conf.
>
> [*] Improvements
> * Snort startup messages printed in syslog now contain a PID before each
> entry. Thanks Sekure for initially bringing this up.
>
> * Stream4: Performance improvements.
>
> * Stream4: Added 'max_session_limit' option which limits number of
> concurrent sessions tracked. Added favor_old/favor_new options that
> affect order in which packets are put together for reassembly.
>
> * Stream4: New configuration options to manage flushpoints for improved
> anti-evasion. The flush_behavior option selects flushpoint management
> mode. New flush_base, flush_range, and flush_seed manage randomized
> flushing. Check out the snort.conf file for full config data on the
> new flush options.
>
> * Added two more alerts for BackOrifice client and server packets. This
> allows specific alerts to be suppressed.
>
> * PerfMon preprocessor updated to include more detailed stats for rebuilt
> packets (applayer, wire, fragmented & TCP). Also added 'atexitonly'
> option that dumps stats at exit of snort, and command line -Z flag to
> specify the file to which stats are logged.
>
> * Added new Http Inspect config item, "tab_uri_delimiter," which if
> specified, lets a tab character (0x09) act as the delimiter for a URI.
>
> * Added a '-G' command line flag to snort that specifies the Snort
> instance log identifier. It takes a single argument that can be either
> hex (prefaced with 0x) or decimal. The unified log files will include
> the instance ID when the -G flag is used.
>
> * "Same SRC/DST" (sid 527) and "Loopback Traffic" (sid 528) are now
> handled in the IP decoder. Those sids are now considered obsolete.
>
> * Http_Inspect "flow_depth" option now accepts a -1 value which tells
> Snort to ignore all server-side traffic.
>
> * RPMs have been updated to be more portable, and also now include a
> "--with inline" option for those wanting to build Inline RPMs. Thanks
> Daniel Wittenberg and JP Vossen for your help!
>
> * Many, many bug fixes have also gone into this release, please see the
> ChangeLog for details.
under ${PREFIX} instead of being an absolute path.
So fix the references using RCD_SCRIPTS_EXAMPLEDIR to be
${PREFIX}/${RCD_SCRIPTS_EXAMPLEDIR}.
This should have no changes to use before.
Please note that the MESSAGE files in most cases are wrong in the
first place. We have automated mechanisms and could have an automated
message for explaining rc.d script usage. (This is something to do!)
which installs to ${RCD_SCRIPTS_EXAMPLEDIR}. But the MESSAGE
referred to wrong hard-coded location if the RCD_SCRIPTS_EXAMPLEDIR
was not the default. So use RCD_SCRIPTS_EXAMPLEDIR instead.
PKGREVISION not bumped because if someone had changed
RCD_SCRIPTS_EXAMPLEDIR before recent change of autoregistration
of rc.d script in PLIST, then it could not have been packaged
in first place.
Note that this commit does not imply that the MESSAGE is correct.
In some cases, the MESSAGE is clearly wrong such as suggesting
running the rc.d script from the example directory (which will work
although).
This version fixes the buffer overflow issue noted in:
http://www.kb.cert.org/vuls/id/916785
Changes:
- follow PKG_SYSCONFDIR
- added rc.d script
- create own user and group
- added MESSAGE with post-install instructions
- removed DEINSTALL
- minor cleanups (this package was really half-baked..)
1.9.1:
======
- src/preprocessors/spp_rpc_decode.c (PreprocRpcDecode):
- alignment errors on non-x86 platforms
- added new space delimited options
alert_fragments
no_alert_multiple_requests
no_alert_large_fragments
no_alert_incomplete
- corrected buffer overflow in fragment normalization
- src/snort.c
- Win32 '-s' parameter wasn't configured to accept an optarg,
but code expected one, causing null-pointer violation.
- Backport of 2.0 fixes for stream4 ( off by one errors on reassembly )
