CVE-2022-3775
When rendering certain unicode sequences, grub2's font code doesn't proper 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 an...

CVE-2022-3775
CVE-2022-3775 affects grub2 font rendering (grub_font_construct_glyph). The issue arises when rendering certain unicode sequences: the code does not adequately validate the glyph width/height against the bitmap, causing an out-of-bounds write to grub2 heap, leading to memory corruption and potent...

AZL-11604 CVE-2022-2601 affecting package grub2 for versions less than 2.06-8
A buffer overflow was found in grubfontconstructglyph. A malicious crafted pf2 font can lead to an overflow when calculating the maxglyphsize value, allocating a smaller than needed buffer for the glyph, this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may...
grub2: Heap based out-of-bounds write when redering certain unicode sequences
A flaw was found in the grub2 font code. When rendering certain unicode sequences, it fails to properly validate the font width and height. These values are further used to access the font buffer, causing possible out-of-bounds writes. A malicious actor may craft a font capable of triggering this...
