The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2019-4668 advisory.

    [1:1.2-5.el7]
    - Update spec file to remove 'modprobe kvm-intel' and remove --enable-kvm arg to ovmf_vars_generator so     qemu will not require kvm kernel module. (Aaron Young)
    - Update spec file to modprobe kvm_intel module prior to running qemu to enroll default keys. (Aaron     Young)
    - Enroll Oracle cert/key for OL secureboot support. (Aaron Young)

    [1:1.2-2.el7]
    - Change Image.c image load error to DEBUG_WARN from DEBUG_ERROR since it is normal for some images to     fail to load if the associated hardware is not present. Such is the case with Ramfb. (Aaron Young)     [Orabug: 28868674]
    - Fix AAVMF build. Pull in OpenSSL code (as is done for x86_64) (Aaron Young)
    - Update AAVMF change log for version 1.2 (Aaron Young)

    [1:1.2-1.el7]
    - Update spec files and OVMF change log to version 1.2

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6920-1 advisory.

    It was discovered that EDK II was not properly performing bounds checks in Tianocompress, which could lead     to a buffer overflow. An authenticated user could use this issue to potentially escalate their privileges     via

    local access. (CVE-2017-5731)

    It was discovered that EDK II had an insufficient memory write check in the SMM service, which could lead     to a page fault occurring. An

    authenticated user could use this issue to potentially escalate their privileges, disclose information     and/or create a denial of service via local access. (CVE-2018-12182)

    It was discovered that EDK II incorrectly handled memory in DxeCore, which could lead to a stack overflow.
    An unauthenticated user could this issue to potentially escalate their privileges, disclose information

    and/or create a denial of service via local access. This issue only affected Ubuntu 18.04 LTS.
    (CVE-2018-12183)

    It was discovered that EDK II incorrectly handled memory in the Variable service under certain     circumstances. An authenticated user could use this issue to potentially escalate their privileges,     disclose

    information and/or create a denial of service via local access. (CVE-2018-3613)

    It was discovered that EDK II incorrectly handled memory in its system firmware, which could lead to a     buffer overflow. An unauthenticated user could use this issue to potentially escalate their privileges     and/or

    create a denial of service via network access. This issue only affected Ubuntu 18.04 LTS. (CVE-2019-0160)
