.NET Core Lifecycle News

Ubuntu 14.04 reached the end of standard support April 2019. We will no longer produce and release packages for this OS version.

.NET Core 1.0 and 1.1, which entered "Maintenance" support status when 2.1 was declared LTS, will be end-of-life June 27, 2019. Updates for the 1.0 and 1.1 channels will no longer be offered after that date. See .NET Core Support Policy to learn more about the .NET Core support lifecycle.

Changes in 2.1.11

.NET Core 2.1.11 release carries both security and non-security fixes.

Microsoft is releasing this security advisory to provide information about a vulnerability in .NET Core 1.0, 1.1, 2.1 and 2.2. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.

A denial of service vulnerability exists when .NET Core improperly process RegEx strings. 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 applications handle RegEx string processing.
