Syncplify Server! v6.2.26 released

Importance of this update: [HIGH]
What’s changed?
  • Upgraded the compiler to the latest version, which comes with many fixes in the compiler’s standard library
  • Huge improvement in Protector(TM) performance, strikes are now counted up to 1000x faster than before
  • Added STSPreload to the global configuration in the SuperAdmin UI
  • Slightly relaxed RSA key security requirements to restore functionality of PKI authentication using old and insecure RSA keys (only when already known to the server prior to the changes made to prevent Terrapin)
  • Upgraded back-end SyngoDB database server to v4.11.0

IMPORTANT NOTE: those who are running the “worker” system service under a different account (not System or LocalSystem) will need to re-configure the service to run under such account after upgrading from any version number <= 6.1.12)

Upgrading from v6.x.y is a simple and fairly automatic process: simply download the latest version from the official download page, and install it over the existing version, all of your settings and license will be kept.

If, instead, you’re upgrading from an older (v4/v5) version, you find the upgrade instructions in our knowledge base.

Thank you all for trusting our software with your secure file transfers!

Upgrade to v6.2.21 now (and be safe from the Terrapin Attack)

Every once in a while something happens that shakes up an entire industry. This is one such time.

The Terrapin Attack (CVE-2023-48795) affected practically every SSH server from every vendor on the planet. And though the bug wasn’t in our own code, we inherited it from Go’s ssh package, so our server software ended up being affected as well.

Kudos to the Go developers who identified and fixed the issue before the CVE was even made public! We will be forever grateful to them, as their timeliness allowed us to release v6.2.21 before this problem affected any of our customers.

We did our part, now it’s all up to you: to make sure your Syncplify Server! is protected from the Terrapin Attack, please, upgrade to v6.2.21+ with the utmost level of urgency. Thank you!
