CVE-2020-15706 [MEDIUM] CWE-362 CVE-2020-15706: GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnera GRUB2 contains a race condition in grub_script_function_create() 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 version 2.04 and prior versions.

CVE-2020-15707 [MEDIUM] CWE-362 CVE-2020-15707: Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efili Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init 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 large number of arguments to the initrd command

CVE-2020-15705 [MEDIUM] CWE-347 CVE-2020-15705: GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to 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. This issue affects GRUB2 version 2.04 and prior versions
