Security advisories
Tuxera is committed to delivering reliable, safe, and secure products and services. Security advisories are published to document remediation for potential security issues and vulnerabilities identified with Tuxera products. Tuxera engineers issue a security advisory when mitigation is available, and will not publicly publish any details that could potentially be used to comprise products in order to reduce or eliminate risks. Critical information is disclosed directly to our strategic partners and customers or authorized distributors in a timely manner as required, related to the risk and the scope of the issue. We respect the security considerations of all customers and will not provide advanced details outside of established channels.

| TUXSA-2021-0001 | NTFSPROGS | Older versions than NTFSPROGS 3021.4.15.8 | Upgrade to NTFSPROGS 3017.7.18.22 or 3021.4.15.8 | These vulnerabilities may allow an attacker with both physical access to a device and a maliciously crafted NTFS-formatted USB or other external storage to potentially execute arbitrary code. If the NTFS tool is configured to run automatically when an external storage is plugged into the device, then the code would execute in user space with the same privileges as the NTFS tool used (typically ntfsck) which is usually root. These vulnerabilities result from incorrect validation of some of the NTFS metadata that could potentially cause buffer overflows, which could be exploited by an attacker. Therefore, an attacker needs to have local or physical access to the target to exploit these vulnerabilities. Common ways for attackers to gain physical access to a machine is through social engineering or an evil maid attack on an unattended device. | Moderate | 2021-08-30 | 2021-08-30 |
| TUXSA-2021-0002 | NTFSPROGS | Older versions than NTFSPROGS 3021.4.15.8 | Upgrade to Tuxera NTFS 3017.7.18.22 or 3021.4.15.8 for QNX, Nucleus, INTEGRITY, Windows Automotive and Linux user space | These vulnerabilities may allow an attacker with both physical access to a device and a maliciously crafted NTFS-formatted USB or other external storage to potentially execute arbitrary code with the same privileges as the NTFS driver when the external storage is plugged into the device. These vulnerabilities result from incorrect validation of some of the NTFS metadata that could potentially cause buffer overflows, which could be exploited by an attacker. Therefore, an attacker needs to have local or physical access to the target to exploit these vulnerabilities. Common ways for attackers to gain physical access to a machine is through social engineering or an evil maid attack on an unattended device. | Moderate | 2021-08-30 | 2021-08-30 |
| TUXSA-2022-0001 | NTFSPROGS Tuxera NTFS | Older versions than NTFS 3021.4.23.18 and NTFSPROGS 3021.4.15.12 | Update to NTFS kernel driver 3021.4.23.18 and to NTFSPROGS 3021.4.15.12 | These vulnerabilities may allow an attacker with both physical access to a device and a maliciously crafted NTFS-formatted USB or other external storage to potentially execute arbitrary code. These vulnerabilities result from incorrect validation of some of the NTFS metadata that could potentially cause buffer overflows, which could be exploited by an attacker. Therefore, an attacker needs to have local or physical access to the target to exploit these vulnerabilities. | Moderate | 2022-10-18 | 2022-10-18 |
