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)

CVE-2018-14680, CVE-2018-14681, CVE-2018-14682: more fixes for embedded
 libmspack. (bsc#1103040)
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:
 [link moved to references] Restore exit code compatibility of freshclam with versions before
 0.100.0 when the virus database is already up to date (bsc#1104457).");
