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.

  - 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)

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

  - Improper input validation in .NET allows an unauthorized attacker to elevate privileges locally.
    (CVE-2026-35433)

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