[GLSA-200405-03] ClamAV VirusEvent parameter vulnerability

Vulnerability Assessment Summary
ClamAV VirusEvent parameter vulnerability

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200405-03
(ClamAV VirusEvent parameter vulnerability)


The VirusEvent parameter in the clamav.conf configuration file permits to
specify a system command to run whenever a virus is found. This system
command can make use of the "%f" parameter which is replaced by the name of
the file infected. The name of the file scanned is under control of the
attacker and is not sufficiently checked. Version 0.70 of clamav disables
the use of the "%f" parameter.

Impact

Sending a virus with a malicious file name can result in execution of
arbirary system commands with the rights of the antivirus process. Since
clamav is often associated to mail servers for email scanning, this attack
can be used remotely.

Workaround

You should not use the "%f" parameter in your VirusEvent configuration.
