The Microsoft .NET Core installations on the remote host are missing a security update. It is, therefore, affected by multiple vulnerabilities as referenced in the vendor advisory.

  - Allocation of resources without limits or throttling in .NET allows an unauthorized attacker to deny     service over a network. (CVE-2026-47302, CVE-2026-50525, CVE-2026-50651)

  - Improper verification of cryptographic signature in .NET allows an unauthorized attacker to bypass a     security feature over a network. (CVE-2026-47304)

  - Improper validation of specified type of input in .NET Framework allows an unauthorized attacker to deny     service over a network. (CVE-2026-50524)

  - Improper link resolution before file access ('link following') in .NET allows an authorized attacker to     perform tampering locally. (CVE-2026-50526)

  - Stack-based buffer overflow in .NET Framework allows an unauthorized attacker to deny service over a     network. (CVE-2026-50527)

  - Incorrect authorization in .NET allows an unauthorized attacker to bypass a security feature over a     network. (CVE-2026-50528)

  - Protection mechanism failure in .NET Framework allows an unauthorized attacker to execute code locally.
    (CVE-2026-50646)

  - Allocation of resources without limits or throttling in .NET Framework allows an unauthorized attacker to     deny service over a network. (CVE-2026-50648)

  - Deserialization of untrusted data in .NET allows an unauthorized attacker to execute code locally.
    (CVE-2026-50649)

  - Improper control of generation of code ('code injection') in .NET Framework allows an unauthorized     attacker to elevate privileges locally. (CVE-2026-50650)

  - Improper encoding or escaping of output in .NET allows an authorized attacker to perform spoofing over a     network. (CVE-2026-50659)

  - Access of resource using incompatible type ('type confusion') in .NET Core allows an unauthorized attacker     to deny service over a network. (CVE-2026-57108)
