Article Information

This article applies to the following ZCS versions.

ZCS 8.0 Article ZCS 8.0

For those using ZCS 8.0.6 and prior, come 22 October 2016 anti-virus definitions will no longer update AND your ClamAV instance will stop working entirely.

EOL Source: http://blog.clamav.net/2016/05/clamav-097-engine-end-of-life.html

Preventative methods

-Update ZCS to a newer version.

-Update just the ClamAV component.

Past EOL ?

-Turn off ClamAV from your admin console > server > services 'as/av' tab > uncheck av. Via CLI it's zmprov ms `zmhostname` -zimbraServiceEnabled Antivirus. (The minus sign is important, or you'll leave nothing but av running.) Then zmamavisdctl reload. (This may leave you more vulnerable of course.)

-Update just the ClamAV component.

Manual ClamAV component upgrade:

Zimbra includes ClamAV 0.98.4 as of ZCS 8.0.7+. The clamav-0.95.1 directory from an installed ZCS 8.0.7 or later installation can be copied directly to an earlier ZCS 8.0/7.2.x server. To upgrade ClamAV, perform the following steps:


Redhat 6.x: clamav-0.98.4.tar.gz md5 sha256

CentOS 6.x: clamav-0.98.4.tar.gz md5 sha256

SLES 11 64-bit: clamav-0.98.4.tar.gz md5 sha256

Ubuntu 10.04 64-bit: clamav-0.98.4.tar.gz md5 sha256

Ubuntu 12.06 64-bit: clamav-0.98.4.tar.gz md5 sha256

Other methods to obtain

1. Install a new server with a later release of ZCS or use the above links. The Free Open-Source release of ZCS is available at http://www.zimbra.com/downloads/os-downloads.html. This document was tested with 8.5.1 (8.0.9 for Ubuntu 10), but any release starting with 8.0.7 or later will work. 2. After the installation is complete, tar up clamav-0.95.1 on the new server:

cd /opt/zimbra
tar cf /tmp/clamav-0.98.4.tar clamav-0.98.4

The Actual Update Instructions

3. Copy this tar file to your existing ZCS server.

cd /opt/zimbra
scp user@server:/tmp/clamav-0.98.4.tgz.

4. Untar the file.

tar xzf clamav-0.98.4.tgz

5. Stop ZCS services.

zmcontrol stop

6. Change the symbolic link

rm clamav
ln -s clamav-0.98.4 clamav
ls -l clamav

The output line will look similar to:

lrwxrwxrwx  1 root root 25 Apr  9 15:39 clamav -> /opt/zimbra/clamav-0.98.4

7. Start services.

zmcontrol start


You can confirm that the new version of ClamAV is running by checking /opt/zimbra/log/clamd.log. The most recent startup in the log should look similar to: Sat Oct 22 18:42:31 2016 -> +++ Started at Sat Oct 22 18:42:31 2016 Sat Oct 22 18:42:31 2016 -> clamd daemon 0.98.4 (OS: linux-gnu, ARCH: x86_64, CPU: x86_64)

Test send-recieve of mail.

With ClamAV 0.98 in place, updates should continue uninterrupted after October 22, 2016, and your system will remain protected.

This procedure was tested using ZCS 8.5.1 (and ZCS 8.0.9 for Ubuntu 10).
