Further, issues were found in image loading that could potentially lead to memory overflows.
For Debian 10 buster, these problems have been fixed in version 2.06-3~deb10u2.
We recommend that you upgrade your grub2 packages.
For the detailed security status of grub2 please refer to its security tracker page at: [link moved to references]
