New in .NET Core Runtime 2.1.0 (May 31, 2018)

  • Installer changes:
  • The .NET Core installers now support package manager updates (eg apt-get update) functionality.
  • Supported version changes:
  • In with the new - .NET Core 2.1 is available for Ubuntu 18.04 and Fedora 28.
  • Out with the 'old' - Fedora 26 moves to end-of-life on 5/30/2018 and will be removed from the list of .NET Core supported operating systems.
  • Snap support:
  • We have been working on bringing .NET Core to Snap and are ready to hear what you think. Snaps, along with a few other technologies, are an emerging application installation and sandboxing technology which we think is pretty intriguing. The Snap install works well on Debian-based systems and other distros such as Fedora are having challenges that we're working to run down. The following steps can be used if you would like to give this a try.

New in .NET Core Runtime 2.0.5 (Jan 10, 2018)

  • CVE-2018-0786 - Security Feature Bypass in X509 Certificate Validation:
  • Microsoft is aware of a security vulnerability in the public versions of .NET Core where an attacker could present a certificate that is marked invalid for a specific use, but a component uses it for that purpose. This action disregards the Enhanced Key Usage tagging.

  • CVE-2018-0764 - Denial of Service when parsing XML documents:
  • Microsoft is aware of a Denial of Service vulnerability in all public versions of .NET core due to improper processing of XML documents. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to a .NET Core application.
  • The update addresses the vulnerability by correcting how .NET core handles XML document processing.

  • NETStandard 2:
  • An incredible number of APIs have been added to NETStandard2. See Announcing NETStandard2 for details.
  • High Sierra:
  • .NET 2.0 has been tested on macOS High Sierra to ensure compatibility. Please start an conversation in dotnet/core #812 if issues are encountered.
  • Docker Images:
  • The .NET Core Docker images have been updated for this release. Look for the 2.0.0 images.
  • Installer Package Name Changes:
  • We received much feedback that our names and versions were confusing and generally messy. Great discussions were had with contributors to craft a plan which is implemented in Preview 2. You can see the conversation and details in dotnet/designs/issues/2 and dotnet/core-setup/issues/1599.
  • Server Hosting Bundles:
  • Because the Runtime Package Store contains crossgen'ed files for a specific release, the hosting bundles will now install side-by-side. This will allow for previous applications to retain the performance benefits while applications targeting new Core versions will at the same time make use of the updated Store.
  • Support:
  • .NET Core 2.0 is being released as a 'current' release. See the .NET Core support document for details on release types. We have also posted OS Lifecycle Support Policy detailing OS version policies.
