antivirus application server. 

The installed version of ViRobot Linux Server has a flaw such that an
attacker can bypass authentication and gain access to its 'filescan'

may be able to leverage this flaw to delete arbitrary files on the
remote host or disable access to the service by submitting scans of a
large number of large files on the remote host." );
