The remote Windows host has an antivirus application that is affected by a path traversal vulnerability.
The remote Windows host is running Avast Antivirus with a virus definition prior to version 150918-0. It is, therefore, affected by a path traversal vulnerability that occurs when processing ZIP archives. An unauthenticated, remote attacker can exploit this, via a crafted ZIP archive, to delete or write arbitrary files to the system.
Upgrade the Avast Antivirus virus definition to version 150918-0 or later.
