The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:3593 advisory.

    .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 7.0.107 and .NET Runtime 7.0.7.

    The following packages have been upgraded to a later upstream version: dotnet7.0 (7.0.107). (BZ#2211876)

    Security Fix(es):

    * dotnet: .NET Kestrel: Denial of Service processing X509 Certificates (CVE-2023-29331)

    * dotnet: vulnerability exists in NuGet where a potential race condition can lead to a symlink attack     (CVE-2023-29337)

    * dotnet: Elevation of privilege - TarFile.ExtractToDirectory ignores extraction directory argument     (CVE-2023-32032)

    * dotnet: Remote Code Execution - Source generators issue can lead to a crash due to unmanaged heap     corruption (CVE-2023-33128)

    * dotnet: Bypass restrictions when deserializing a DataSet or DataTable from XML (CVE-2023-24936)
