    Debian Bug     : 1014468 1060408 1084055 1061256

    Multiple security vulnerabilities have been fixed in EDK II, a modern,
    feature-rich, cross-platform firmware development environment. Remotely
    exploitable buffer overflows and out-of-bounds or infinite loop
    vulnerabilities may lead to a denial of service or the execution of
    arbitrary code.

    For Debian 11 bullseye, these problems have been fixed in version
    2020.11-2+deb11u3.

    We recommend that you upgrade your edk2 packages.

    For the detailed security status of edk2 please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/edk2
