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.

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)
