Synology released a security update for DiskStation Manager 6. DSM 6.0.1-7393-2 applies the workaround to mitigate a security vulnerability of libupnp module (CVE-2016-6255).
The update did not do a full reboot (although the release notes say a manual reboot is required for systems using Wi-Fi dongles) but it does restart several services. I seen restarts for QuickConnect, Audio Station, Download Station, Media Station and Video Station. This isn’t a complete list so you should anticipate other services being restarted.
