DATE CVE VULNERABILITY TITLE RISK
2020-07-29 CVE-2020-15707 Integer Overflow or Wraparound vulnerability in multiple products
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.
4.4
2020-07-29 CVE-2020-15706 Use After Free vulnerability in multiple products
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.
6.4
2020-07-29 CVE-2020-15705 Improper Verification of Cryptographic Signature vulnerability in multiple products
GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed.
