Descriptions
In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode is loaded in the function ntfs_inode_real_open, a heap buffer overflow can occur allowing for code execution and escalation of privileges.
En NTFS-3G versiones anteriores a 2021.8.22, cuando es cargado un inodo NTFS especialmente diseñado en la función ntfs_inode_real_open, puede ocurrir un desbordamiento del búfer de la pila, permitiendo una ejecución de código y una escalada de privilegios
The ntfs3g package is susceptible to a heap overflow on crafted input. When processing NTFS inodes, 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.
