https://notcve.org/view.php?id=CVE-2020-15705
29 Jul 2020 — 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. GRUB2 presenta un fallo al comprobar la firma del kernel cuando se inicia directamente sin cuña, permitiendo que el arranque seguro sea omitido. Esto solo afe... • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00067.html • CWE-347: Improper Verification of Cryptographic Signature CWE-440: Expected Behavior Violation •

CVE-2020-15706 – GRUB2 contains a race condition leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing.

CVE-2020-15707 – GRUB2 contained integer overflows when handling the initrd command, leading to a heap-based buffer overflow.
https://notcve.org/view.php?id=CVE-2020-15707
28 Jul 2020 — 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 on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI ... • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00016.html • CWE-190: Integer Overflow or Wraparound CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
