Comment 10 Marcus Meissner 2022-11-16 10:15:31 UTC

CVE-2022-2601 grub2: A buffer overflow in grub_font_construct_glyph() can lead to out-of-bound write and possible secure boot by-pass
6.4/CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H

A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted
pf2 font can lead to an overflow when calculating the max_glyph_size 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 use this
vulnerability to circumvent the secure boot mechanism.
