Server Software and Configuration Services
Changes:
– Added IPV6_SPI workaround for CentOS/RedHat v5 and custom kernels that do not support IPv6 connection tracking by opening ephemeral port range 32768:61000. This is only applied if IPV6_SPI is not enabled. This is the same workaround implemented by RedHat in the sampe default IPv6 rules
cPanel v11.36 has now entered the STABLE tree and you will notice that most of your addon perl scripts failing. You can resolve this easily with our addons by reinstalling them. We have provided a simple script that can do this for you that we posted previously. This has to be done regardless as to whether you are running the latest versions:
This script will update: cmm, cmc, cmq, cse, csf, cxs, msinstall, msfe
Only those scripts that are already installed will be updated. Those that are updated are done so regardless as to whether they are the same or an older version of those available.
To use this method you must be logged into root via SSH to the server and then run:
curl -s configserver.com/free/csupdate | perl
You should take care to read through the output to ensure that all the upgrades have worked as expected.
Changes:
– Fixed issue with processing /proc/PID/stat for process information
Changes:
– Prevent csf/lfd from failing to run if a non-critical configuration file does not exist
– In webmin, force table stylesheet to override webmin css. Requires webmin module reinstall on existing installations
Changes:
– Improvements to minimal perl module detection on new installs
– Bugfix for default lfd.pl perl shebang
Changes:
– Implement slurp routine for configuration files to cater for incorrect linefeeds
– Ignore leading and trailing spaces from lines in configuration files
– Fixed Include statements in csf.ignore not implemented in lfd
– Additional debug logging for RT_*_LIMIT added
– Replaced call to Time::HiRes::sleep with standard sleep
– Additional dovecot entries in csf.pignore for new installations
Changes:
– Switched from using LWP to HTTP::Tiny to reduce memory footprint and reliance on the LWP perl module. The HTTP::Tiny module is included in the distribution, so no further action is necessary
– Modified lfd perl module loading to be conditional where possible to reduce lfd memory footprint
– Modify initial file processing to reduce lfd memory footprint
– Modify PS_PORTS processing to reduce lfd memory footprint
– Moved init of Geo::IP::PurePerl into iplookup subroutine
– Removed “DEFERRED” login failure checking from CPANEL_LOG regex due to false-positives
– Modify LF_DIRWATCH_DISABLE so that only files are added to suspicious.tar and removed. Suspicious directories will no longer be removed
– Removed File::Path – no longer required
Changes:
– Modify MESSENGER HTML header to return code 403 instead of 200
– Modify UI daemon to fallback to IPv4 if IPV6 setting is not enabled
– Added new options LF_SYMLINK and LF_SYMLINK_PERM. This feature enables detection of repeated Apache symlink race condition triggers from the Apache patch provided by:
http://www.mail-archive.com/dev@httpd.apache.org/msg55666.html
This patch has also been included by cPanel via the easyapache option:
“Symlink Race Condition Protection”

Changes:
– Ensure all binaries are called with their full paths for the scheduled Server Security Check reports
– Allow csf -u/-uf/–update and -c/–check when csf is disabled
– Make RT_* checks IPv6 compatible
– Added dns query caching for ip lookups during lfd process lifetime
– Modify TOR rule loading to use FASTSTART in lfd if enabled
– Added iptables locking to FASTSTART code
– LF_INTERVAL now defaults to 3600 on new installations to better cope with slow brute force login attempts
– Removed references to .cpanel.net being ignored from the changelog as they no longer apply and could cause confusion
– Fix csf.rignore loader regex causing unnecessary DNS lookups if file has no entries
– Added “DEFERRED” login failure checking to CPANEL_LOG regex
