CVE-2022-3775 grub2: Heap based out-of-bounds write when redering certain unicode sequences
6.3/CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H

When rendering certain unicode sequences, GRUB2's font code doesn't properly
validate if the informed glyph's width and height is constrained within bitmap
size. As consequence an attacker can craft an input which will lead to
a out-of-bounds write into GRUB2's heap, leading to memory corruption and
availability issues. Although complex, arbitrary code execution could not
be discarded.
