Actually, looks like this was fixed already. The 30s ReceiveTimeout default value was being set in eoan's clamav-freshclam.postinst:
[ -z "$ReceiveTimeout" ] && ReceiveTimeout=30 This was later changed to 0 in the package version 0.102.2+dfsg-1: clamav (0.102.2+dfsg-1) unstable; urgency=medium * Import 0.102.2 - CVE-2020-3123 (DoS may occur in the optional DLP feature) (Closes: 950944). * Update symbol file. * Set ReceiveTimeout to 0 which is upstream default. Which is in Ubuntu Focal. Therefore, this bug is fixed in that upcoming release. -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to clamav in Ubuntu. https://bugs.launchpad.net/bugs/1865511 Title: Tweak freshclam ReceiveTimeout value for slow internet connections To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/clamav/+bug/1865511/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
