CVE-2024-45776

CVE-2024-45776 affects GRUB2’s language handling (grub_mofile_open): reading a language .mo file can overflow the internal buffer during allocation due to an unchecked integer overflow, leading to out-of-bounds reads/writes. Consequences described in the sources include leakage of sensitive data ...

CVE-2024-45776 Grub2: grub-core/gettext: integer overflow leads to heap oob write and read.

When reading the language .mo file in grubmofileopen, grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak sensitive data o...
