Problems with ClamAV v0.90RC

Please note that as of writing you should not upgrade ClamAV to v0.90RC. The Mail::ClamAV perl module (v0.17) will not compile with this version of ClamAV installed and will therefore break MailScanner.For now you should remain on ClamAV v0.88.5 until either the ClamAV or the Mail::ClamAV developers resolve the issue.

New MailScanner Front-End (MSFE) v3.5

We’ve completely reworked the WHM part of the MailScanner Front-End to put much of the control into the WHM UI in a similar manner as our csf WHM UI. You can see the latest screenshots which show the new features (bottom row):http://www.configserver.com/cp/msfe.htmlChanges:

  • Corrected versioning system
  • Flattened installation procedure
  • Complete rewrite of the WHM MailScanner Front-End

If you wish to upgrade MSFE and have purchased an installation service package from us in the past, email sales@waytotheweb.com and we’ll provide you with a download account for http://download.webumake.com

New csf v2.37

Changes:

  • Added canna to the Security Check
  • New feature – added support for dynamic dns (DYNDNS) records. See csf.conf for more information
  • Added dyndns file edit to WHM UI

New ClamAV v0.88.5

Changes:

  • fixes a crash in the CHM unpacker and a heap overflow inthe function rebuilding PE files after unpacking.

Upgrade:

  • Upgrade through WHM MSFE or by following:http://www.configserver.com/cp/upgrade.html

New csf v2.36

Changes:

  • Added runlevel check to Security Check
  • Added nobody cron check to Security Check
  • Added melange server check to Security Check
  • Modified the regex for the php.ini disable_functions check
  • Added timing function to lfd that logs how long each stage takes. This can be enabled by editing lfd.pl and setting $timing=1 – this can help in tracking down performance issues with lfd

New MailScanner Script v2.46

Changes:

  • Modified installer script to change the exim system_filter to an empty file (/etc/antivirus.empty) instead of periodically emptying /etc/antivirus.exim
  • Modified installer script to check for existence, ownership and permissions on the spool directories on upgrade
  • Modified installer script to cleanly stop and start MailScanner without Failed messages
  • Latest MailSCanner v4.56.8
  • Modified installer script to offer second option for new installations to skip forced perl module installation
  • Fixed bug in the MailScanner distribution where the MailScanner.conf update script isn’t chmod executable

New csf v2.35

Changes:

  • Added specific exclusion for proftpd in lfd.pl process tracking
  • Fixed bug with GLOBAL_LF being ignored

New csf v2.34

New feature:

  • Added a new option (beta for now) PT_SMTP. This option will check for outgoing connections to port 25, ecluding root, exim and mailman. The purpose of the feature is to log SMTP connections if you believe you have a spammer on the server who is bypassing exim to send out spam emails – this is traditionally a very difficult form of spam to track down. The option currently logs relevant process information to lfd.log to avoid an email alert flood.

Serious cPanel Security Problem

A major security flaw has been found and is being actively exploited in cPanel. The exploit gives an authenticated user (i.e. someone who has access to a cPanel account) an escalation that gives them root access. cPanel have fixed the hole and most people will have been secured overnight. To be sure I would suggest everyone runs a forced upcp update on their servers:

/scripts/upcp –force
