The remote Ubuntu 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6161-1 advisory.

    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)

The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 2023_Jun_13 advisory.

  - .NET, .NET Framework, and Visual Studio Denial of Service Vulnerability (CVE-2023-29331)

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

The Microsoft Visual Studio Products are missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - A remote code execution vulnerability in the MSDIA SDK where corrupted PDBs can cause heap overflow,     leading to a crash or remote code execution. (CVE-2023-24897)

  - A remote code execution vulnerability where specially crafted input to git apply -reject can lead to     controlled content writes at arbitrary locations. (CVE-2023-25652)

  - A spoofing vulnerability where Github localization messages refer to a hard-coded path instead of     respecting the runtime prefix that leads to out-of-bound memory writes and crashes. (CVE-2023-25815)

  - An Out-Of-Bounds Write Vulnerability in Autodesk FBX SDK version 2020 or prior may lead to code     execution through maliciously crafted FBX files or information disclosure. (CVE-2023-27909)

  - An information disclosure vulnerability where a user may be tricked into opening a malicious     FBX file. This may exploit a stack buffer overflow (CVE-2023-27910) or heap buffer overflow     (CVE-2023-27911) vulnerability in Autodesk FBX SDK 2020 or prior which may lead to remote code     execution. 

  - A remote code execution vulnerability where a configuration file containing a logic error results     in arbitrary configuration injection. (CVE-2023-29007)

  - A remote code execution vulnerability where the Git for Windows executable responsible for     implementing a SOCKS5 proxy is susceptible to picking up an untrusted configuration on multi-user     machines. (CVE-2023-29011)

  - A remote code execution vulnerability where the Git for Windows Git CMD program incorrectly     searches for a program upon startup, leading to silent arbitrary code execution. (CVE-2023-29012)

  - A remote code execution vulnerability in the .NET SDK during tool restore which can lead to an     elevation of privilege. (CVE-2023-33135)

  - An information disclosure vulnerability by the obj file parser in Visual Studio. (CVE-2023-33139)
