"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has ovmf packages installed that are affected by
multiple vulnerabilities:

  - Bounds checking in Tianocompress before November 7, 2017 may allow an authenticated user to potentially
    enable an escalation of privilege via local access. (CVE-2017-5731)

  - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was in a CNA pool
    that was not assigned to any issues during 2017. Notes: none. (CVE-2017-5732, CVE-2017-5733,
    CVE-2017-5735)

  - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by
    its CNA. Notes: none. (CVE-2017-5734)

  - Stack overflow in corrupted bmp for EDK II may allow unprivileged user to potentially enable denial of
    service or elevation of privilege via local access. (CVE-2018-12181)

  - Logic issue in variable service module for EDK II/UDK2018/UDK2017/UDK2015 may allow an authenticated user
    to potentially enable escalation of privilege, information disclosure and/or denial of service via local
    access. (CVE-2018-3613)

  - Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to
    timing attacks via a side-channel timing attack on 'port contention'. (CVE-2018-5407)

  - Buffer overflow in system firmware for EDK II may allow unauthenticated user to potentially enable
    escalation of privilege and/or denial of service via network access. (CVE-2019-0160)

  - Stack overflow in XHCI for EDK II may allow an unauthenticated user to potentially enable denial of
    service via local access. (CVE-2019-0161)

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