CVE-2023-4693 – Grub2: out-of-bounds read at fs/ntfs.c
https://notcve.org/view.php?id=CVE-2023-4693
An out-of-bounds read flaw was found on grub2's NTFS filesystem driver. This issue may allow a physically present attacker to present a specially crafted NTFS file system image to read arbitrary memory locations. A successful attack allows sensitive data cached in memory or EFI variable values to be leaked, presenting a high Confidentiality risk. Se encontró una falla de lectura fuera de los límites en el controlador del sistema de archivos NTFS de grub2. Este problema puede permitir que un atacante físicamente presente presente una imagen del sistema de archivos NTFS especialmente manipulada para leer ubicaciones de memoria arbitrarias. • https://access.redhat.com/errata/RHSA-2024:2456 https://access.redhat.com/errata/RHSA-2024:3184 https://access.redhat.com/security/cve/CVE-2023-4693 https://bugzilla.redhat.com/show_bug.cgi?id=2238343 https://dfir.ru/2023/10/03/cve-2023-4692-cve-2023-4693-vulnerabilities-in-the-grub-boot-manager https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/FUU42E7CPYLATXOYVYNW6YTXXULAOV6L https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.or • CWE-125: Out-of-bounds Read •
