.NET and Visual Studio Remote Code Execution Vulnerability

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - .NET and Visual Studio Remote Code Execution Vulnerability (CVE-2024-38229)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0727 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2024-38229:
    A flaw was found in dotnet. When closing an HTTP/3 stream while application code is writing to the     response body, a race condition can cause a use-after-free.

    CVE-2024-43483:
    A flaw was found in dotnet. The System.Security.Cryptography.Cose, System.IO.Packaging and     System.Runtime.Caching components may be exposed to hostile input, making them susceptible to hash     flooding attacks, resulting in denial of service.

    CVE-2024-43484:
    .NET, .NET Framework, and Visual Studio Denial of Service Vulnerability

    CVE-2024-43485:
    .NET and Visual Studio Denial of Service Vulnerability
