"The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has ovmf packages installed that are affected by
multiple vulnerabilities:

  - 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)

  - 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)

  - 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)

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

  - 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)

  - 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)
