Red Hat Security Advisory: dotnet3.1 security update
Notes
Topic
An update for dotnet3.1 is now available for Red Hat Enterprise Linux 8.
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 Core 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 Core that address security vulnerabilities are now available. The updated versions are .NET Core SDK 3.1.104 and .NET Core Runtime 3.1.4.
Security Fixes:
* dotnet: Denial of service via untrusted input (CVE-2020-1108)
* dotnet: Denial of service due to infinite loop (CVE-2020-1161)
Default inclusions for applications built with .NET Core have been updated to reference the newest versions and their security fixes.
