CVE-2021-39255

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 attr find in attrdef function of the NTFS-3G file system driver. This can be triggered by a crafted NTFS image, allowing an attacker to access confidential data, compromise its integrity, and potentially cause a denial of service. The exploitation is caused by an invalid attribute in the ntfs attr find in attrdef function.

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 access to NTFS images from untrusted sources to minimize the risk of exploitation.
