Original advisory details:

 It was discovered that .NET did not properly enforce certain
 restrictions when deserializing a DataSet or DataTable from
 XML. An attacker could possibly use this issue to elevate their
 privileges. (CVE-2023-24936)

 Kevin Jones discovered that .NET did not properly handle the
 AIA fetching process for X.509 client certificates. An attacker
 could possibly use this issue to cause a denial of service.
 (CVE-2023-29331)

 Kalle Niemitalo discovered that the .NET package manager,
 NuGet, was susceptible to a potential race condition. An
 attacker could possibly use this issue to perform remote
 code execution. (CVE-2023-29337)

 Tom Deseyn discovered that .NET did not properly process certain
 arguments when extracting the contents of a tar file. An attacker
 could possibly use this issue to elevate their privileges. This
 issue only affected the dotnet7 package. (CVE-2023-32032)

 It was discovered that .NET did not properly handle memory in
 certain circumstances. An attacker could possibly use this issue
 to cause a denial of service or perform remote code execution.
 (CVE-2023-33128)");
