Name of the Vulnerable Software and Affected Versions NTFS-3G versions prior to 2021.8.22

Description The issue is related to a heap buffer overflow that can occur when a specially crafted NTFS inode pathname is supplied in an NTFS image. This can result in memory disclosure, denial of service, and potentially even code execution. The vulnerability allows an attacker to access confidential data, compromise its integrity, and cause a denial of service.

Recommendations For versions prior to 2021.8.22, update to version 2021.8.22 or later to resolve the issue. As a temporary workaround, consider restricting the use of specially crafted NTFS inode pathnames in NTFS images to minimize the risk of exploitation.
