Descriptions

In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode pathname is supplied in an NTFS image a heap buffer overflow can occur resulting in memory disclosure, denial of service and even code execution.

En NTFS-3G versiones anteriores a 2021.8.22, cuando se suministra un nombre de ruta de inodo NTFS especialmente diseñado en una imagen NTFS, puede ocurrir un desbordamiento del búfer de la pila, resultando en una divulgación de memoria, una denegación de servicio e incluso una ejecución de código

The ntfs3g package is susceptible to a heap overflow on crafted input. When processing an NTFS inode pathname, proper bounds checking was not enforced leading to this software flaw. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
