High [CVE-2023-4692] out-of-bounds write at fs/ntfs.c may lead to unsigned code execution
CVE-2023-4692Source published Source updated
An out-of-bounds write flaw was found in grub2's NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub's heap metadata corruption. In some circumstances, the attack may also corrupt the UEFI firmware heap metadata. As a result, arbitrary code execution and secure boot protection bypass may be achieved. This vulnerability is considered as 'Low' severity by Red Hat as the NTFS module is not shipped as part of Red Hat's signed grub2 image. Weakness: CWE-122. Affected Red Hat products: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat Enterprise Linux 7. Red Hat fixing advisory: RHSA-2024:3184, RHSA-2024:2456. Affected products named by the advisory: Red Hat package: grub2.
