Security Advisory:

---

A security vulnerability was identified in the open source NTFS-3G and NTFSPROGS software. The vulnerability was confirmed and resolved and to our knowledge, vulnerability has not been exploited.

This vulnerability may allow an attacker using a maliciously crafted NTFS-formatted image file or external storage to potentially execute arbitrary privileged code, if the attacker has either local access and the ntfs-3g binary is setuid root, or if the attacker has physical access to an external port to a computer which is configured to run the ntfs-3g binary or one of the ntfsprogs tools when the external storage is plugged into the computer. This vulnerability results from incorrect validation of some of the NTFS metadata that could potentially cause buffer overflow, which could be exploited by an attacker. Common ways for attackers to gain physical access to a machine is through social engineering or an evil maid attack on an unattended computer.

We recommend installing and applying the update with the security fixes, and advise to follow security guidance and frameworks such as NIST for assessing and improving an organization’s abilities to prevent, detect, and respond to security threats and cyber attacks.

AFFECTED PRODUCTS: All previous versions of open source NTFS-3G and NTFSPROGS.

WORKAROUND: None

SOLUTION: Upgrade to version 2022.10.3
