As consequence an attacker can craft an input which will lead to a out-of-bounds write into grub2&#39;s heap, leading to memory corruption and availability issues. Although complex, arbitrary code execution could not be discarded.</p> <p><strong>Affected:</strong> grub2</p> <p>When rendering certain unicode sequences, grub2&#39;s font code doesn&#39;t proper validate if the informed glyph&#39;s width and height is constrained within bitmap size.
