Synology has updated DiskStation Manager 5.1 to version 5.1-5021. The update includes (from the Synology DSM release notes):
Version:5.1-5021
What’s New
This update includes all bug fixes as well as security fixes in the previously released critical updates since DSM 5.1-5004.
Fixed Issues
Enhanced data security by disabling “Mount automatically on start-up” after restoring an encrypted shared folder.
Fixed a vulnerability that allows senders to access unintended destinations during a backup job.
Enhanced stability on Amazon S3 on large file backup.
Upgraded OpenVPN to 2.3.6 to address a security vulnerability.
Fixed a vulnerability that allows local users to initiate a denial of service by queuing the maximum number of file descriptors (CVE-2014-7824).
Upgraded PHP to 5.5.19 to address multiple vulnerabilities (CVE-2014-3669, CVE-2014-3670, CVE-2014-3668, and CVE-2014-3710).
Improved DTV dongle compatibility.
Improved file-copying stability on DS2015xs.
Fixed an issue where DS213+ and DS413 could power up unexpectedly when backup tasks are scheduled.
Minor bug fixes.
Synology has also updated many of their packages (a.k.a. applications) with minor enhancements and bug fixes. Of the packages I use, the following have been updated:
Audio Station
Cloud Station
Cloud Sync
Download Station
Note Station
Video Station
All the changes are minor, the only one I personally noticed is that Note Station now sorts the Notebooks in the sidebar list which makes them easier to find.
I updated both my Synology DS415+ and Synology DS212+ without having a problem.
