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...

DEBIAN-CVE-2022-2601

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...

CVE-2022-2601

The CVE-2022-2601 issue is a vulnerability in grub2’s font rendering path: a crafted pf2 font causes an overflow in grub_font_construct_glyph(), which can allocate too small a buffer for a glyph and trigger a heap-based out-of-bounds write. This vulnerability can be exploited to bypass Secure Boo...

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...

grub2: Buffer overflow in grub_font_construct_glyph() can lead to out-of-bound write and possible secure boot bypass

A flaw was found where a maliciously crafted pf2 font could lead to an out-of-bounds write in grub2. A successful attack can lead to memory corruption and secure boot circumvention...
