Synopsis

The remote Red Hat host is missing one or more security updates for .NET Core on Red Hat Enterprise Linux.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:0134 advisory.

.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 3.0.102, .NET Core Runtime 3.0.2, .NET Core SDK 3.1.101 and .NET Core Runtime 3.1.1.

Security Fixes:

* dotnet: Memory Corruption in SignalR (CVE-2020-0603)

* dotnet: SignalR Denial of Service via backpressure issue (CVE-2020-0602)

Users must rebuild their applications to pick up the fixes.

Default inclusions for applications built with .NET Core have been updated to reference the newest versions and their security fixes.

For more details about the security issues, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE pages listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
