Summary
Red Hat Security Advisory: .NET 5.0 on Red Hat Enterprise Linux security and bugfix update

Notes

Topic
An update for rh-dotnet50-dotnet is now available for .NET on Red Hat Enterprise Linux. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
.NET is a managed-software framework. It implements a subset of the .NET framework APIs and several new APIs, and it includes a CLR implementation. New versions of .NET that address a security vulnerability are now available. The updated versions are .NET SDK 5.0.203 and .NET Runtime 5.0.6. Security Fix(es): * dotnet: .NET Core single-file application privilege escalation (CVE-2021-31204) In order for the update to be complete, self-contained applications deployed using previous versions need to be recompiled and redeployed. For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
