"The Microsoft Access Products are missing a security update. They are, therefore, affected by multiple vulnerabilities:

  - Heap-based buffer overflow in Microsoft Office Access allows an authorized attacker to execute code
    locally. (CVE-2026-69477)

  - Heap-based buffer overflow in Microsoft Office Access allows an unauthorized attacker to execute
    code over a network. (CVE-2026-69529, CVE-2026-69778)

  - Stack-based buffer overflow in Microsoft Office Access allows an unauthorized attacker to execute
    code over a network. (CVE-2026-69614)

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