CVE-2023-32032

.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)

.NET and Visual Studio Elevation of Privilege Vulnerability

.NET and Visual Studio Elevation of Privilege Vulnerability

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)
