Integer overflow

Integer overflows were discovered in the functions grubcmdinitrd and grubinitrdinit in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu the functionality is not included in GRUB2 upstream, leading to a heap-based buffer overflow. These could be triggered by an extremely...

Race condition

GRUB2 contains a race condition in grubscriptfunctioncreate leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2...

CVE-2020-15707

CVE-2020-15707 is a GRUB2 bootloader vulnerability (initrd size handling) causing a heap-based buffer overflow via integer overflow in initrd processing. The flaw affects GRUB2 2.04 and earlier as deployed in multiple distros (Debian, Red Hat, Ubuntu) and can enable arbitrary code execution durin...

CVE-2020-15705 GRUB2: avoid loading unsigned kernels when GRUB is booted directly under secureboot without shim

GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim...
