Mageia 6 :: x86_64

Installed the packages before updating and also installed clamtk, the gui frontend.
$ clamtk
This reported that the database needed to be updated.
$ freshclam
That contacted clamav.net, failed on the incremental update and downloaded the daily.cvd

There is a PoC for CVE-2018-1000085 in the form of a bsae64 encoded file.  It is not
clear how to use it.  Decoded it, hopefully:
$ base64 -d poc.base64 > poc
$ clamtk
Selected 'file' and pointed clamav at poc.
Scanned and reported "no threats found".  ??
Either the file was not properly decoded or it needs to be tested in a different way.
Note that the upstream analysis depended on ASAN.

Updated the packages:
- clamav-0.99.4-1.mga6.x86_64
- clamav-db-0.99.4-1.mga6.noarch
- clamav-milter-0.99.4-1.mga6.x86_64
- clamd-0.99.4-1.mga6.x86_64
- clamtk-5.20-3.1.mga6.noarch
- lib64clamav-devel-0.99.4-1.mga6.x86_64
- lib64clamav7-0.99.4-1.mga6.x86_64
- lib64oxygen-gtk-1.4.6-3.mga6.x86_64
- oxygen-gtk-1.4.6-3.mga6.x86_64

Ran up clamtk and changed the settings.  Unchecked all but 'Scan directories
Scanned user Downloads directory - 735 files - no threats found.
Checked the poc as well and as expected - no threats found.  

This update looks OK.
