Clamav was updated to version 0.100.2 :

CVE-2018-15378: Vulnerability in ClamAV's MEW unpacking feature that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. (bsc#1110723)

Make freshclam more robust against lagging signature mirrors.

On-Access 'Extra Scanning', an opt-in minor feature of OnAccess scanning on Linux systems, has been disabled due to a known issue with resource cleanup OnAccessExtraScanning will be re-enabled in a future release when the issue is resolved. In the mean-time, users who enabled the feature in clamd.conf will see a warning informing them that the feature is not active. For details, see:
https://bugzilla.clamav.net/show_bug.cgi?id=12048

Restore exit code compatibility of freshclam with versions before 0.100.0 when the virus database is already up to date (bsc#1104457).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
