## Description

Mahara 17.04 before 17.04.8 and 17.10 before 17.10.5 and 18.04 before
18.04.1 can be used as medium to transmit viruses by placing infected files
into a Leap2A archive and uploading that to Mahara. In contrast to other
ZIP files that are uploaded, ClamAV (when activated) does not check Leap2A
archives for viruses, allowing malicious files to be available for
download. While files cannot be executed on Mahara itself, Mahara can be
used to transfer such files to user computers.
