Vulnerability Assessment Details
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.
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.
You should not use the "%f" parameter in your VirusEvent configuration.
All users of Clam AntiVirus should upgrade to the latest stable version:
# emerge sync
# emerge -pv ">=net-mail/clamav-0.70"
# emerge ">=net-mail/clamav-0.70"
Network Security Threat Level: High
