  script_tag(name:"insight", value:"This update for clamav fixes the following issues:

  clamav was updated to version 0.100.2.

  The following security issues were fixed:

  - 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)

  The following non-security issues were addressed:

  - 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.

  - 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-15:Update update project.
