Clamav and freshclam database update error
« on: August 01, 2021, 11:53:34 AM »
After updating to centos-release-7-9.2009.1.el7.centos.x86_64 and CWPpro version: 0.9.8.1078
I received mails with erros from this script: Cron <root@server> /usr/share/clamav/freshclam-sleep > /dev/null

Code: [Select]
ERROR: cdiff_apply: lseek(desc, -350, SEEK_END) failed
ERROR: downloadPatch: Can't apply patch

It seems related to this issue from Clamav: https://blog.clamav.net/2021/07/psa-freshclam-database-download-issue.html

They suggest this solution:
If you are experiencing this same issue, the simplest solution is to delete your signature databases from /var/lib/clamav. Then, make sure your FreshClam configuration in /etc/clamav/freshclam.conf either has the ReceiveTimeout option set sufficiently high (E.g. 300 seconds). Alternatively, users can remove the ReceiveTimeout option entirely to disable the timeout.

After making these changes, you may re-enable your FreshClam service or run freshclam manually and you should find that it is working correctly again.
