Contents and detection

A list of the improvements for the Contents and Detection that have been introduced in this release.

Improved the handling of files with spaces when Sandbox extracts and unarchives files.
Improved the SIGN:TRAFFIC-MALFORMED alerts for UDP and GOOSE packets, considering now legitimate declared packet lengths that are smaller than the real packet.
The risk for the SIGN:PROTOCOL-INJECTION alert has been lowered to 6. It now also belongs to the High security profile.
Improved secure shell (SSH) banner detections are now enabled by default.
The firmware version used in the Common Platform Enumeration (CPE)s for ONVIF nodes detected passively or through Smart Polling is now more accurate.
Improved the concurrency of storage operations for the quarantine directory for Sandbox.
Increased the likelihood for node_cpes for onvif to 0.8.
