Synology released updates for both DiskStation Manager 5 and DiskStation Manager 6 with security related fixes. The DSM 5 updated had one patch while the DSM 6 update killed several bugs. Also note, while there’s no official word from Synology, it looks like the update for DSM 6 may have been pulled back.
The main focus of these patches is to patch the badlock vulnerability which was shamelessly hyped. It’s not as bad as the lead-up made it sound, but it should still need to be patched. It’s less important in home or small networks where everyone is trusted (or already has complete access). Someone already needs access to your local network in order to exploit the vulnerability.

DSM 5 is updated to version 5.2-5644-8.. This fixed a security vulnerability regarding Samba file service (CVE-2016-2118, also known as Badlock).
