[client+server] Applied patch from Franck Joncourt to remove unnecessary chmod() call when creating client rc file and server replay cache file. The permissions are now set appropriately via open(), and at the same time this patch fixes a potential race condition since the previous code used fopen() followed by chmod().

- Suggested the idea for setting an access stanza expiration time.
|
|
- Suggested the abiliy to have certain incoming connections automatically
|
|
NAT'd through to specific internal systems. The result was the FORCE_NAT
|
|
mode.
|
|
- Assisted with getting fwknop running under the Pentoo Linux distro.

Andy Rowland
|
|
- Reported a bug where the same encryption key used for two stanzas in the
|
|
access.conf file would result in access requests that matched the second
|
|
stanza to always be treated as a replay attack. This has been fixed for
|
|
the fwknop-2.0.1 release.

- Caught a bug where the default PCAP_LOOP_SLEEP value was 1/100th of a
|
|
second instead of the intended default of 1/10th of a second.

- fwknop Debian package maintainer.
|
|
- Contributed a new Debian init script.
|
|
- Contributed a patch to have the perl FKO module link against libfko in
|
|
the local directory (if it exists) so that it doesn't have to have libfko
|
|
completely installed in /usr/lib/. This allows the test suite to run FKO
|
|
tests without installing libfko.

- Contributed a patch to remove unnecessary chmod() call when creating

client rc file and server replay cache file. The permissions are now set

appropriately via open(), and at the same time this patch fixes a

potential race condition since the previous code used fopen() followed by

- Submitted patches to change HTTP connection type to 'close' for -R mode
|
|
in the client and fix a bug for recv() calls against returned HTTP data.

- Reported an issue with the Morpheus client sending SPA packets with NULL
|
|
IP addresses, and code was added to fwknopd to better validate incoming
|
|
SPA data as a result of this report.
|
|
|
|
Geoff Carstairs
|
|
- Suggested a way to redirect valid connection requests to a specific
|
|
internal service via NAT, configurable by each stanza in access.conf.
|
|
This allows for better access control for multple users requiring access
|
|
to multiple internal systems, in a manner that is transparent to the
|
|
user. The result was the FORCE_NAT mode.
|
|

|
Hank Leininger
|
|
- For iptables firewalls, suggested a check for the 'comment' match to
|
|
ensure the local environment will properly support fwknopd operations.
|
|
The result is the new ENABLE_IPT_COMMENT_CHECK functionality.

|
|
- Found important buffer overflow conditions for authenticated SPA clients
|
|
in the fwknopd server (pre-2.0.3). These findings enabled fixes to be
|
|
developed along with a new fuzzing capability in the test suite.
|
|
- Found a condition in which an overly long IP from malicious authenticated
|
|
clients is not properly validated by the fwknopd server (pre-2.0.3).
|
|
- Found a local buffer overflow in --last processing with a maliciously
|
|
constructed ~/.fwknop.run file. This has been fixed with proper
|
|
validation of .fwknop.run arguments.
|
|
- Found several conditions in which the server did not properly throw out
|
|
maliciously constructed variables in the access.conf file. This has been
|
|
fixed along with new fuzzing tests in the test suite.

|
|
- Submitted a patch to fix ndbm/gdbm usage when --disable-file-cache is
|
|
used for the autoconf configure script. This functionality was broken in
|
|
be4193d734850fe60f14a26b547525ea0b9ce1e9 through improper handling of
|
|
#define macros from --disable-file-cache.
|
|
- Submitted a patch to fix command exec mode under SPA message type
|
|
validity test. Support for command exec mode was also added to the test
|
|
suite.
|
|
- Submitted an OpenBSD port for fwknop-2.0.3, and this has been checked in
|
|
under extras/openbsd/.
