   An update that fixes four vulnerabilities is now available.

Description:

   This update for clamav fixes the following issues:

   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)
   - 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:
     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).
