"The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by
multiple vulnerabilities as referenced in the USN-7060-1 advisory.

    It was discovered that EDK II did not check the buffer length in XHCI,

    which could lead to a stack overflow. A local attacker could potentially use this issue to cause a denial
    of service. This issue only affected

    Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2019-0161)

    Laszlo Ersek discovered that EDK II incorrectly handled recursion. A remote attacker could possibly use
    this issue to cause EDK II to consume resources, leading to a denial of service. This issue only affected

    Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2021-28210)

    Satoshi Tanda discovered that EDK II incorrectly handled decompressing certain images. A remote attacker
    could use this issue to cause EDK II to crash, resulting in a denial of service, or possibly execute
    arbitrary code. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2021-28211)

    It was discovered that EDK II incorrectly decoded certain strings. A remote attacker could use this issue
    to cause EDK II to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue
    only

    affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2021-38575)

    It was discovered that EDK II had integer underflow vulnerability in

    SmmEntryPoint, which could result in a buffer overflow. An attacker could potentially use this issue to
    cause a denial of service. (CVE-2021-38578)

    Elison Niven discovered that OpenSSL, vendored in EDK II, incorrectly

    handled the c_rehash script. A local attacker could possibly use this

    issue to execute arbitrary commands when c_rehash is run. This issue

    only affected Ubuntu 16.04 LTS. (CVE-2022-1292)
