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

Description The issue is related to an out-of-bounds read in the ntfs ie lookup function of the NTFS-3G driver for the FUSE module. This can be exploited by a crafted NTFS image, potentially allowing an attacker to access confidential data, compromise data 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 NTFS images from untrusted sources to minimize the risk of exploitation.
