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. (CVE-2021-28210)

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
