In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode pathname is supplied in an NTFS image a heap buffer overflow can occur resulting in memory disclosure, denial of service and even code execution.

Security readout for executives and security teams

This flaw affects NTFS-3G before 2021.8.22. A malicious NTFS filesystem image can trigger a heap buffer overflow when NTFS-3G handles a crafted inode pathname, potentially causing data exposure, service crash, or code execution. Exposure is most likely on Linux or Unix-like systems that use NTFS-3G to mount or process NTFS volumes, especially removable drives, disk images, forensic workflows, or user-supplied media. Prioritize remediation where NTFS-3G handles untrusted media or disk images. The code-execution potential makes this more than a routine crash bug, but urgency is tempered by no cited active exploitation. Mitigation focus: Upgrade NTFS-3G to version 2021.8.22 or a vendor-fixed package.; Apply relevant Debian, Fedora, Gentoo, or other distribution security updates.; Restrict automatic mounting of untrusted NTFS media where practical..
