.NET and Visual Studio Denial of Service Vulnerability

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2022:0830 advisory.

  - A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the     input length of a one-shot decompression request to a script can trigger a crash, which happens when     copying over chunks of data larger than 2 GiB. It is recommended to update your Brotli library to 1.0.8 or     later. If one cannot update, we recommend to use the streaming API as opposed to the one-shot API, and     impose chunk size limits. (CVE-2020-8927)

  - .NET and Visual Studio Denial of Service Vulnerability (CVE-2022-24464)

  - .NET and Visual Studio Remote Code Execution Vulnerability (CVE-2022-24512)

The Microsoft .NET core installations on the remote host are missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - A denial of service (DoS) vulnerability. An attacker can exploit this issue to cause the affected     component to deny system or application services. (CVE-2022-24464)

  - A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2020-8927, CVE-2022-24512)

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:
