Thanks to Neohapsis (http://archives.neohapsis.com/archives/fulldisclosure/2012-12/0108.html) for finding this.
Added NULL pointer checks after memory allocating function calls
Changelog for CGI vulnerability updates
Fixed bug #401: segmentation fault on Solaris when parsing unknown timeperiod directives.

Previously the end of the function xodtemplate_parse_timeperiod_directive 
was referencing a pointer after it had been freed (and NULLed). This 
has been corrected.
Changed check results utility functions to accept list pointer.

In order to make the check results utility functions more generic, they have
been changed to accept a check results list pointer rather than using the 
global check_results_list. This will enable these function to be used to 
manipulate temporary lists without impacting the system's global list of
check results.

This change is being made in anticipation of implementing a function to 
see which checks are still executing at a Nagios restart so those checks
are not rescheduled incorrectly as a result of the restart.
Change ownership on debug log file

Previously, when the debug log file was opened, it was opened before Nagios
dropped privileges. If the debug log file did not exist, it would be created
by the privileged owner (root). Because the default umask is 022, it 
would be mode 644. If Nagios received a HUP signal, it close and attempt 
to reopen the file as the unprivileged user, which would fail. 

This patch changes ownership on the debug log file in the drop_privilegeds()
function once the uid and gid for the unprivileged user have been determined.
Fixed bug #408 - service checks get duplicated on reload.

If a check is still running when Nagios is restarted or reloaded (via SIGHUP),
Nagios will now look for running checks and mark them as executing. Then, when
the checks are scheduled before the execution loop starts, the running checks
will be not be rescheduled. They will be rescheduled as usual when their 
results are reaped.

This commit also re-introduces the extra event debug logging that was 
unintentionally removed between versions 3.4.2 and 3.4.3.
Updated version for 3.4.4-rc1 release candidate
Re-enabled update check that was turned off in commit 1854
