"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).

This update was imported from the SUSE:SLE-12:Update update project."
