Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1802 advisory.

    Heap-based buffer overflow in .NET allows an unauthorized attacker to elevate privileges locally.
    (CVE-2026-32177)

    Loop with unreachable exit condition ('infinite loop') in ASP.NET Core allows an unauthorized attacker to     deny service over a network. (CVE-2026-42899)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues 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:

  - Heap-based buffer overflow in .NET allows an unauthorized attacker to elevate privileges locally.   (CVE-2026-32177)

  - A tampering vulnerability exists when .NET Core improperly handles specially crafted files. An attacker   who successfully exploited this vulnerability could write arbitrary files and directories to certain   locations on a vulnerable system. However, an attacker would have limited control over the destination of   the files and directories. To exploit the vulnerability, an attacker must send a specially crafted file to   a vulnerable system. The security update fixes the vulnerability by ensuring .NET Core properly handles   files. (CVE-2026-32175)

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

The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the vendor advisory.
