    - ------------------------------------------------------------------------- Debian Security Advisory DSA-5280-1 security@debian.org https://www.debian.org/security/ Steve McIntyre November 15, 2022 https://www.debian.org/security/faq

    Package : grub2
    CVE ID : CVE-2022-2601 CVE-2022-3775

    Several issues were found in GRUB2's font handling code, which could
    result in crashes and potentially execution of arbitrary code. These
    could lead to by-pass of UEFI Secure Boot on affected systems.

    Further, issues were found in image loading that could potentially
    lead to memory overflows.

    For the stable distribution (bullseye), these problems have been fixed in version 2.06-3~deb11u4.

    We recommend that you upgrade your grub2 packages.

    For the detailed security status of grub2 please refer to its security
    tracker page at:
