Synology® Inc. today releases the latest DSM 5.0-4458 Update 2 to resolve the vulnerability CVE-2014-0160 (also known as the Heartbleed bug) in the OpenSSL software.

  • For users running DSM 5.0, please follow the instructions on Security Advisory to update DSM and renew SSL certification.
  • DSM 4.3 users are advised to update their systems to DSM 5.0. If users want to stay in DSM 4.3, patch will be ready by the end of April.
  • DSM 4.1 users are advised to upgrade their systems to DSM 4.2, while patch for DSM 4.2 will be delivered in one week.
  • DSM 4.0 and previous versions are not affected.
